Cyma is not a household name the way Rolex or Omega is, but it has quietly earned a spot in Swiss watchmaking history that goes back further than most of its more famous neighbors. Founded in the mountains of the Jura in 1862, the brand built a reputation on precision movements, tough waterproof cases, and a role supplying watches to soldiers during World War II. Today, Cyma is mostly known and loved among collectors who hunt for its vintage pieces, which means learning about the brand is really learning about a slice of watchmaking history rather than shopping a current catalog. Here is what makes Cyma worth knowing about, whether you already own one or you just found a weathered example in a family drawer.
Brand History
Cyma started in 1862 when brothers Joseph and Theodore Schwob set up a small watch workshop in La Chaux-de-Fonds, Switzerland. The Schwob brothers picked the name from an old Latin word for “sprout,” a nod to French cime, meaning peak or summit — a fitting bit of wordplay for two young men trying to build something from the ground up. In the early days, the operation was tiny: a staff of about 40 people running 55 machines, turning out roughly 40 watches a day by hand and simple tooling.
The real turning point came thirty years later. In 1891, engineer Henri Sandoz took over a watch factory in the town of Tavannes and built it into a serious manufacturing operation, applying early mass-production methods that let the company grow from a handful of workers to producing well over a hundred watches a day. The Schwob brothers’ sales network merged with Sandoz’s factory, and the combined business created the Cyma brand specifically to sell what the factory produced. That partnership is why vintage collectors often see “Cyma” and “Tavannes” on the same dial or movement — for decades, the two names were essentially the same company wearing different hats.
By the early 1900s, Cyma was already competing with the biggest names in Swiss horology. The company won a gold medal at the 1893 World’s Columbian Exposition in Chicago, and in 1905 it introduced Caliber 701, an unusually thin movement that earned a chronometer certificate from the Neuchâtel Observatory. Cyma also pushed early into water resistance, one of the areas it became best known for. Waterproof Cyma watches appeared as early as 1915, and diving-friendly designs stayed a signature of the brand for decades afterward.
Cyma’s most famous chapter arrived during World War II. The British Ministry of Defence needed a huge number of durable, waterproof, legible watches for soldiers, and it turned to twelve Swiss manufacturers to fill the order — a group collectors now nickname the “Dirty Dozen.” Cyma was one of them, and its version stood out for using higher-grade steel than some competitors managed during wartime shortages. Between the twelve companies involved, wartime Swiss factories are estimated to have turned out somewhere around 145,000 of these standardized watches for British forces.
After the war, Cyma kept innovating with alarm watches and automatic movements through the 1950s and 60s, but the back half of the twentieth century was rougher. Cyma and its sister brand Tavannes went into steep decline through the 1960s, with production stopping altogether by 1966, before new owners restarted manufacturing under a different corporate umbrella a couple of years later. The Cyma name has changed hands more than once since then and today exists mainly as a heritage brand, better known through the vintage pieces collectors trade than through a large current lineup of new watches.
What Makes Cyma Watches Special?
Cyma watches stand out because they were engineered by a company that actually made its own parts, at a time when many rivals were assembling movements bought from outside suppliers. That in-house approach shows up in a whole list of technical firsts and specialties Cyma is credited with, and taken together, they explain why collectors still take the brand seriously today.
- In-house manufacturing. Cyma and its sister company Tavannes made most of their own movements rather than buying them from outside suppliers, which was unusual even among respected Swiss brands of the era. This gave Cyma direct control over quality and let it develop features on its own timeline instead of waiting on a third-party movement maker.
- Early water resistance. Waterproof Cyma watches appeared as early as 1915, decades before water resistance became a standard feature across the watch industry. That early head start carried through to later dedicated dive and sport models like the Navystar and Watersport.
- Shock resistance and patents. By the 1960s, Cyma held around 20 international patents covering shock protection, water sealing, and case construction, technology it branded as “Cymaflex” and built into models across its lineup.
- Chronometer-grade precision. Cyma earned official chronometer certification on multiple movements over the decades, including its 1905 Caliber 701 and the 1956 gold Time-O-Vox alarm watch, proving the brand could match dress-watch precision even in tool watches.
- In-house alarm watch expertise. Very few Swiss brands attempted to build their own alarm wristwatch movements. Cyma did, and its calibers were reliable enough that other watch companies used Cyma-made movements in their own alarm watches.
- Wartime military heritage. Cyma’s role as one of the “Dirty Dozen” British military watch suppliers during World War II gives the brand a documented, verifiable piece of history that few other affordable vintage brands can claim.
- Practical design solutions. Details like the Cymaflex bracelet’s spring-connected links, built to flex and fit different wrist sizes without a clasp, show a brand more interested in solving real wearing problems than chasing trends.
That combination — real engineering substance, wartime history, and a habit of solving practical problems rather than just decorating a dial — is what separates Cyma from brands that built their reputation on marketing alone.
Top 10 Best Cyma Watches
Because Cyma today is mostly known through its historical output rather than a large current product line, this list covers the most notable and sought-after Cyma models across the brand’s history — the watches collectors specifically look for. A quick note on the tables below: since these are vintage references produced across many decades without a surviving modern factory archive, exact case sizes and specs can vary a little between individual examples and dealer listings, so treat the figures as commonly cited ranges rather than fixed factory numbers.
1. Cyma WWW “Dirty Dozen” Military Watch (1940s)
This is the watch most people associate with Cyma today. Issued to British soldiers during World War II, it has a black dial, luminous Arabic numerals, and the military “broad arrow” stamp marking it as government property. This model used the Cyma Caliber 234, a chronometer-rated manual movement, and surviving examples are commonly cited among the biggest-cased pieces in the whole “Dirty Dozen” set, with some references measuring around 38mm across. Original examples in good condition are genuinely rare and command strong prices among military watch collectors.
| Detail | Information |
|---|---|
| Era | 1940s (WWII military issue) |
| Case size | Roughly 36–38mm, depending on reference |
| Case material | Stainless steel |
| Movement | Manual wind, Caliber 234, chronometer-rated |
| Water resistance | Built to the wartime W.W.W. (Watch, Wristlet, Waterproof) standard |
| Known for | British MoD broad arrow marking; part of the “Dirty Dozen” |
2. Cyma Cymaflex (1950s–60s)
The Cymaflex line is remembered for its clever bracelet as much as the watch itself. Instead of a standard clasp, the 35mm Cymaflex used a stretchable metal band built from small interlocking links held together under spring tension, so the whole bracelet could stretch open and snap back to grip a range of wrist sizes. It is a fun example of Cyma solving a practical, everyday annoyance with real engineering rather than just adding another decorative detail.
| Detail | Information |
|---|---|
| Era | 1950s–1960s |
| Case size | Around 35mm |
| Case material | Stainless steel, with gold-cased variants also seen |
| Movement | Manual wind; caliber varies by specific reference |
| Water resistance | Cymaflex shock and seal technology, not a fixed depth rating |
| Known for | Spring-tensioned flexible bracelet that adjusts to wrist size |
3. Cyma Time-O-Vox (1956)
An alarm watch that actually works well is hard to build, and Cyma pulled it off. By 1956, a gold-cased version of the Time-O-Vox had earned official chronometer status, a genuinely rare achievement for a watch that also had to fit an alarm mechanism inside the same case. Collectors prize these for the single-mainspring alarm mechanism, which was unusual compared to the twin-barrel systems used by some rivals.
| Detail | Information |
|---|---|
| Era | Mid-1950s (chronometer-certified gold example dated 1956) |
| Case size | Around 34mm |
| Case material | 18K gold on the certified example; steel versions also exist |
| Movement | Manual wind, Caliber R.464, single-mainspring alarm |
| Water resistance | Not a dedicated dive or sport watch |
| Known for | Chronometer-certified mechanical alarm function |
4. Cyma Navystar (1955 debut, expanded 1960s)
The Navystar is arguably Cyma’s flagship name. It debuted in 1955 as an automatic watch and became one of the first model names Cyma ever gave a specific product line, at a time when most of its output was sold on brand reputation alone rather than named collections. Later versions added serious water resistance and shock protection, and the design proved durable enough that Cyma brought it back with an updated release in 2000.
| Detail | Information |
|---|---|
| Era | 1955 debut, expanded through the 1960s, reissued in 2000 |
| Case size | Varies by generation; 1960s sport versions ran larger than the original |
| Case material | Stainless steel |
| Movement | Automatic; specific caliber varies by generation |
| Water resistance | Reported up to 200m on later 1960s sport versions |
| Known for | Cyma’s flagship named model line and shock/water-resistance flagship |
5. Cyma Watersport (1960s)
Launched alongside the Navystar’s most advanced era, the Watersport was Cyma’s answer to the growing demand for genuinely dive-capable watches. It shared the brand’s shock-resistant Cymaflex protection system and reflected Cyma’s decades-long focus on waterproofing, a specialty the company had been refining since its earliest waterproof cases in the 1910s.
| Detail | Information |
|---|---|
| Era | 1960s |
| Case size | Typical sport-watch sizing for the era; exact figures vary by reference |
| Case material | Stainless steel |
| Movement | Automatic, built with Cymaflex shock protection |
| Water resistance | Dedicated dive-oriented sport model |
| Known for | Sibling model to the Navystar, aimed at underwater durability |
6. Cyma Automatic Wristwatch, Caliber 420 (1943)
This is the watch that started Cyma’s automatic-watch story. In 1943, Cyma released its first self-winding wristwatch, built around a Caliber 420 movement with a unidirectional rotor, years before automatic watches became common across the industry. It’s a quieter piece of history than the wartime military watches, but it laid the technical groundwork for the automatic Navystars and Autorotor models that followed later in the century.
| Detail | Information |
|---|---|
| Era | 1943 |
| Case size | Typical of period dress and everyday watches; varies by reference |
| Case material | Stainless steel or gold-filled, depending on the example |
| Movement | Automatic, Caliber 420, unidirectional rotor |
| Water resistance | Not a dedicated water-resistant model |
| Known for | Cyma’s first self-winding wristwatch |
7. Cyma Autorotor (late 1950s)
The Autorotor mattered because of what it represented: an automatic rotor movement Cyma engineered and built in-house rather than sourcing from an outside supplier. It first appeared in a women’s model before Cyma adapted the same rotor system into a men’s caliber, offered with or without a date function, a year or so later. It ranks among the last major in-house movement developments Cyma introduced before the brand’s fortunes began to slide in the following decade.
| Detail | Information |
|---|---|
| Era | Late 1950s |
| Case size | Varies between the women’s and men’s versions |
| Case material | Stainless steel and gold-cased examples both exist |
| Movement | Automatic rotor, in-house, with or without date function |
| Water resistance | Not a dedicated sport or dive model |
| Known for | Cyma’s own automatic rotor engineering, offered in both women’s and men’s sizing |
8. Cyma Calibre 701 Chronometer (1905)
This one is for the history buffs. The Calibre 701 was an extra-thin movement that helped establish Cyma’s reputation for precision engineering decades before the brand became known for tough sports watches. Original pieces are extremely hard to find today and mostly live in private collections or museum-style archives.
| Detail | Information |
|---|---|
| Era | 1905 |
| Case size | Typical of early-1900s pocket and wristwatch cases |
| Case material | Varies by surviving example, commonly gold or gold-filled |
| Movement | Manual wind, Caliber 701, extra-thin construction |
| Water resistance | Not applicable; predates Cyma’s waterproofing era |
| Known for | Neuchâtel Observatory chronometer certificate for an unusually thin movement |
9. Cyma-Tavannes Chronometer Pocket and Wrist Watches (early 1900s)
Watches from the years when Cyma and Tavannes operated as one combined manufacturing house are especially interesting because they show the brand’s mass-production skill paired with genuine chronometer-grade accuracy, a combination that was not common at the time.
| Detail | Information |
|---|---|
| Era | Early 1900s |
| Case size | Standard pocket watch sizing, with early wristwatch examples smaller |
| Case material | Commonly gold, gold-filled, or silver |
| Movement | Manual wind, chronometer-grade calibers |
| Water resistance | Not applicable |
| Known for | Output from the combined Cyma-Tavannes manufacturing operation |
10. Cyma Art Deco Gold Dress Watches (1920s–1930s)
Away from the tool-watch reputation, Cyma also produced elegant Art Deco pieces during the interwar years, often in gold cushion-shaped cases. These show a completely different side of the brand and are popular with collectors who focus on the design language of that era rather than military or diving history.
| Detail | Information |
|---|---|
| Era | 1920s–1930s |
| Case size | Small by modern standards, typical of Art Deco dress watches |
| Case material | Gold, including 9K and 18K examples |
| Movement | Manual wind, small dress-watch calibers |
| Water resistance | Not applicable |
| Known for | Cushion-shaped Art Deco case design rather than tool-watch features |
What to Consider When Buying
Before buying any Cyma watch, check whether it is a genuine period-correct example rather than a “franken-watch” assembled from mismatched parts. Because Cyma and Tavannes shared movements and cases for decades, it is common to find watches with a case from one era paired with a dial or movement from another. That is not always a problem, but you should know what you are getting and pay a price that reflects it.
Condition of the dial matters more than almost anything else on a vintage Cyma. Original dials, especially on military and alarm models, are hard to replace correctly, and a repainted or “redialed” watch is worth noticeably less to serious collectors than one with its original, aged dial intact. Ask any seller directly whether the dial is original, and if they don’t know, treat that as a red flag rather than a shrug-worthy detail.
- Purpose — Are you buying for everyday wear, as a collectible, or as a piece of family or war history?
- Documentation — Does it come with papers, a box, or military issue markings that can be verified?
- Movement condition — Has it been serviced recently, and by someone experienced with vintage Swiss calibers?
- Water resistance — If it is an old dive or sport model, assume the gaskets need replacing before you get it wet.
- Case originality — Has the case been over-polished, which can soften sharp edges and lower value?
A tip worth remembering: with vintage brands like Cyma, a full service history from a watchmaker who specializes in older Swiss movements is often worth more to your peace of mind than a slightly lower price with no service record at all.
Where to Buy
Cyma is largely a heritage and collector’s brand today, so most buyers find their watches through specialist vintage watch dealers, estate sales, and auction houses that focus on military or mid-century timepieces rather than through a current retail network. Because the brand’s most desirable pieces are decades old, buying from a dealer who can verify authenticity and service history is usually a smarter move than buying blind from an unfamiliar private seller, even if the sticker price looks appealing.
A few sources tend to work better than others depending on what kind of Cyma watch you’re after:
- Specialist vintage and military watch dealers are the safest starting point, especially for WWW “Dirty Dozen” pieces, since these dealers typically inspect movements, verify case markings, and disclose redials or replaced parts up front.
- Watch and militaria auction houses occasionally list Cyma pieces alongside other wartime collectibles, and auction records can also be useful for understanding what a specific model has actually sold for recently.
- Estate sales and inherited collections are where a lot of Cyma watches genuinely surface, since many were bought decades ago and simply passed down rather than resold. These can be excellent value, but you’re on your own for authentication unless you bring in a watchmaker.
- General online marketplaces carry Cyma watches too, but because condition and originality are so important to this brand’s value, treat listings without close-up photos of the movement, case back, and dial as higher risk.
Whichever route you take, ask specifically about service history, whether the dial and hands are original to the watch, and whether any parts have been swapped or replaced. A seller who can answer those questions in detail is generally more trustworthy than one who can’t.
If you inherit or already own a Cyma watch, a reputable independent watchmaker who works on vintage Swiss movements is the right place to start, both for a condition assessment and for repairs. They can also usually point you toward specialist dealers if you decide to sell, and can give you a realistic sense of value before you list it anywhere.
Investment and Resale Value

Vintage Cyma watches occupy an interesting spot in the collector market: genuinely historic, technically impressive, but still priced well below more famous “Dirty Dozen” names like Omega or Longines. That gap has actually made Cyma popular with collectors who want real wartime and mid-century history without paying flagship-brand prices, and several longtime collectors have described the brand as underrated for years, which is often a sign a brand still has room to grow in value rather than one that’s already peaked.
Different Cyma models behave differently as collectibles, so it helps to think about them as separate categories rather than one single market:
- Military WWW models tend to hold their value best of any Cyma watch, particularly examples with original dials, correct case markings, and verifiable military issue numbers stamped on the case back. Because this is the largest-cased watch of the full “Dirty Dozen” set, it also draws interest from collectors chasing the complete twelve-brand set, which supports demand.
- Alarm watches like the Time-O-Vox are more of a niche interest. Values depend heavily on whether the alarm mechanism still functions correctly, since a non-working alarm complication is far less desirable to serious buyers than a purely time-only piece in similar condition.
- Navystar and Watersport sport models sit in the middle of the pack. They’re appealing for their design and durability, but because they were produced in larger numbers than the wartime pieces, supply is easier to find, which keeps prices more moderate.
- Art Deco dress watches attract a different type of buyer entirely, often people collecting for design and era rather than mechanical history, so their value tracks more with condition and gold content than with Cyma’s brand story specifically.
As with most vintage watches, originality drives resale value more than almost any other factor across all of these categories. An honestly worn, all-original Cyma with a documented service history will usually outsell a shinier but over-restored example, even if the restored piece looks better in photos. If you’re buying with resale in mind, prioritize originality and documentation over cosmetic condition alone.
Care and Maintenance
Vintage Cyma watches need the same careful handling as any mechanical watch from the mid-1900s, with a bit of extra caution because parts and documentation are harder to source than for bigger brands. A watchmaker unfamiliar with Cyma’s in-house calibers can sometimes do more harm than good, so it is worth seeking out someone with specific vintage Swiss experience for anything beyond basic cleaning.
Servicing and Wearing
How you wear and service a Cyma matters just as much as how you store it, since day-to-day habits are what put the most strain on an old movement. A little discipline here goes a long way toward keeping a decades-old caliber running smoothly for years to come.
- Get the movement serviced every three to five years, even if the watch seems to be keeping good time, since old lubricants dry out and cause unnecessary wear on the gear train.
- Avoid swimming or showering with a vintage “waterproof” model unless a watchmaker has confirmed the gaskets have been replaced recently — original seals from the 1940s through 60s have almost certainly failed by now, even if the watch looks sealed.
- Wind manual-wind models gently and at roughly the same time each day rather than letting them run down completely and restarting them irregularly, which puts uneven strain on the mainspring over time.
- If the watch has an alarm function, have a specialist check the separate alarm mainspring during servicing, since it wears differently than the timekeeping mainspring and is often overlooked.
- Take the watch off before activities involving strong impacts, magnets, or chemicals like solvents and perfume, all of which can affect an old movement or dial more than they would a modern one.
Storage and Accessories
When a Cyma isn’t on your wrist, how and where you keep it can matter almost as much as how you wear it, since dials, lume, and old lubricants are all sensitive to light, humidity, and rough handling.
- A padded watch box or dedicated watch case keeps the case and crystal protected from scratches and dust when the watch isn’t being worn, and separates it from other jewelry that could scuff the finish.
- Store the watch away from direct sunlight and humidity, since original dials and lume can fade or deteriorate with prolonged exposure — a case or box lined with a stable material, kept in a closet or drawer rather than on a windowsill, works well.
- A soft, lint-free polishing cloth is the safest way to wipe down the case and bracelet after wearing, since rougher materials can leave fine scratches on vintage metal that has already lost some of its original finish.
- If you own an automatic Cyma, like a Navystar or Autorotor model, and you wear it often enough that you don’t want to reset the time and date each time, a watch winder can keep it running between wears — just make sure it’s set to a gentle rotation speed appropriate for an older automatic movement, since some modern winders are calibrated for newer watches and can overwork a delicate vintage rotor system.
- A small silica gel packet or humidity-controlled watch box helps in damp climates, since moisture is one of the more common causes of dial spotting and movement corrosion in old watches.
None of this care is complicated, but it does add up. A Cyma that’s serviced on a reasonable schedule, worn thoughtfully, and stored properly between wears will hold its condition, keep better time, and retain far more of its value than one left to sit in a drawer for decades without attention.
Frequently Asked Questions
Cyma’s mix of wartime history, in-house engineering, and relative obscurity compared to bigger Swiss names tends to raise the same handful of questions, whether you’re a longtime collector or someone who just inherited a Cyma watch and wants to understand what they have. Here are quick, straight answers to the ones that come up most.
Is Cyma still making new watches?
Cyma exists today mainly as a heritage brand rather than a company with a large, actively marketed current lineup. Ownership sits with Stelux International, a Hong Kong-based holdings group with interests in watches and fine jewelry, and industry oversight comes through Universal Genève, a fellow member of the Swiss watch trade federation. Most of what collectors seek out and trade are vintage pieces from the brand’s twentieth-century heyday.
Why is Cyma part of the “Dirty Dozen”?
Cyma was one of twelve Swiss manufacturers chosen by the British Ministry of Defence during World War II to produce standardized “W.W.W.” (Watch, Wristlet, Waterproof) watches for soldiers. Collectors nicknamed this group of twelve brands the “Dirty Dozen,” and Cyma’s version is notable for using higher-quality steel than some wartime shortages allowed for other manufacturers.
How can I tell if my Cyma watch is genuine?
Check that the case, dial, and movement all match the era and reference expected for that model, since Cyma and Tavannes shared parts for decades and mismatched “franken-watches” are common. A watchmaker or specialist dealer experienced with vintage Cyma pieces can usually confirm authenticity by inspecting the movement’s caliber number and case markings.
Are Cyma watches a good investment?
Certain models, especially original military WWW pieces and rare alarm watches in excellent condition, have held or grown in value as collectors rediscover the brand. As with any vintage watch, condition and originality matter far more than the brand name alone when it comes to long-term value.
What is the Cyma Navystar known for?
The Navystar was one of Cyma’s first named model lines, launched in 1955 and later upgraded with serious shock resistance and 200-meter water resistance during the 1960s. Its durable, sporty design proved popular enough that Cyma revived the model with an updated version in the year 2000.
Conclusion
Cyma’s story is really a story about substance winning out over marketing, at least for a while. The brand built its own movements, solved real problems like water resistance and shock protection years ahead of many competitors, and earned a permanent place in wartime history through its role in the “Dirty Dozen.” Its slide out of the spotlight in the second half of the twentieth century means Cyma today lives mostly through the watches collectors still hunt for, from tough military pieces to clever alarm watches like the Time-O-Vox. If you come across a genuine Cyma, whether it is a battered wartime WWW model or a gold Art Deco dress watch, you are holding a piece of real Swiss engineering history that has simply never gotten the attention its technical achievements deserve.
