Yema Navygraf: 70s-Inspired Military Divers

The Yema military diver for those who demand legibility and robustness

The Yema Navygraf collection is born from the heritage of 1970s military divers, translating it into a sea watch designed for real-world use: immediate readability, robust components, and technical details you can feel on the wrist.

Why choose Navygraf

• High water resistance: 200 or 300-meter versions, ideal for water sports and recreational diving.
  
• Performance-oriented crystals and bezels: double-domed sapphire and sapphire bezel inserts on certain variants, for resistance and clarity.
  
• Movements that transform the experience: the CMM.10 manufacture caliber focuses on a power reserve of up to 70 hours and chronometer-grade accuracy; the micro-rotor CMM.20 prioritizes elegance and a slimmer profile without sacrificing the 70-hour power reserve.

The most popular variants

Marine Nationale emphasizes service identity and mil-spec style. Heritage focuses on a philological look with hesalite and warm details. Pearl adds mother-of-pearl and a micro-rotor for a more refined presence. Certain bronze editions offer patina and collectible character.

Choose your Navygraf and wear a credible diver on your wrist, built to last.

Curiosities about the Yema Navygraf

What is the difference between the CMM.10 and the micro-rotor CMM.20?

The CMM.10 is designed for tool-watch use: a large 70-hour power reserve, chronometer-grade accuracy, and a construction focused on robustness. The micro-rotor CMM.20 maintains 70 hours but prioritizes a slimmer profile and a more elegant feel on the wrist.

Navygraf Heritage, Marine Nationale, and Pearl: which one should I choose?

Heritage is the choice for those who want a vintage aesthetic with hesalite and philological details. Marine Nationale centers on military identity and maximum legibility. Pearl adds mother-of-pearl and a micro-rotor for a more refined look without sacrificing its marine vocation.

What does 200 or 300-meter water resistance mean?

It indicates resistance to pressure according to the manufacturer's tests. Both are suitable for swimming and water sports; for recreational diving, the version with the higher specification is preferable. In any case, a well-tightened crown and periodically checked seals make the difference.

How is a diver's bezel used?

Align the zero of the bezel with the minute hand and read the elapsed minutes on the scale. It is a simple method to keep track of diving, training, or navigation times.

How often should an automatic watch be serviced?

On average every 4 to 6 years, depending on use and conditions. After sea or pool use, rinse with fresh water, dry well, and have the water resistance checked if the watch is used frequently in water.
