The exact Yema Navygraf Forces Sous-Marines reference has not been identified in the available official product information. That means its movement, dimensions, water resistance, production status and original price cannot be confirmed from the name alone. Yema’s current Navygraf collection includes variants with different specifications, so figures published for those watches should not be assumed to describe this one.
What is the Yema Navygraf Forces Sous-Marines?
“Yema Navygraf Forces-Sous-Marines” appears in an informal secondhand listing, but no accessible Yema product page identifies a watch under that exact name. Yema describes the Navygraf as its historic 1970s military-grade dive-watch range. That collection history is useful context, but it does not establish the exact history or configuration of a Forces Sous-Marines edition. Yema’s current Navygraf collection
The most reliable way to identify a particular example is to find its reference number on the caseback or warranty card, then match that number to an exact product record. Without that match, details such as caliber, case size, water resistance, production run and launch price remain unverified.
Is it a limited edition, and what movement does it use?
Neither the edition’s limited status nor its movement is established by the exact-edition information available here. Do not infer either from the Forces Sous-Marines wording or from specifications for another Navygraf. Check the watch’s reference number and documentation before treating a seller’s description as confirmed.

Why current Navygraf specifications are not a substitute
Yema’s current Navygraf line includes materially different variants. The Marine Nationale CMM.10 and Marine Nationale Quartz pages illustrate why the family name alone is not enough to identify a watch’s specifications.
| Variant | Published specifications | Source and scope |
|---|---|---|
| Navygraf Marine Nationale CMM.10 | 39 mm 316L steel case; 19 mm lugs; CMM.10 manufacture caliber; 70-hour power reserve; 300 m water resistance; sapphire crystal and unidirectional sapphire bezel; screw-down crown and steel diver bracelet. Yema says the watch includes two straps and a five-year international warranty. | Yema’s current CMM.10 product page, accessed 2026. These are CMM.10 specifications, not verified Forces Sous-Marines specifications. Yema CMM.10 product page |
| Navygraf Marine Nationale Quartz | Seiko VH31 quartz caliber; 39 mm case; 19 mm lugs; 200 m water resistance. | Yema’s separate Quartz product page, accessed 2026. These are Quartz specifications, not verified Forces Sous-Marines specifications. Yema Quartz product page |
Yema states that the CMM.10 caliber is “Designed, manufactured, assembled and calibrated by YEMA’s watchmakers within our Morteau workshops in France.” That statement applies to the CMM.10 caliber; it does not establish the movement in every Navygraf. Yema CMM.10 product page

Franceclat’s 2026 industry publication describes the Navygraf Marine Nationale CMM.10 as designed in collaboration with the French Navy and identifies it as a 300 m dive watch. That is context for the CMM.10, not proof of the Forces Sous-Marines edition’s specifications or military history. Franceclat
What should you verify before buying one?
- Reference: Request a clear caseback photo and a photo of the warranty card or original paperwork. Match the number to an exact product record rather than relying on the model name in an advertisement.
- Movement and condition: Ask for documentation or a watchmaker’s assessment identifying the caliber and describing its condition. The name alone does not confirm whether the watch is mechanical or quartz.
- Water resistance: Do not treat a Navygraf sibling’s rating as evidence for this watch. If water resistance matters, have the specific watch inspected and pressure-tested before exposing it to water.
- Edition status and price: Ask for evidence of any limited production claim and compare like-for-like examples with the same reference and condition. Yema’s current U.S. collection shows Navygraf Marine Nationale watches from $460, but this changing collection price is not a verified original price, availability claim or valuation for a Forces Sous-Marines example. Yema U.S. Navygraf collection
- Strap fit: Confirm lug width and attachment geometry for the exact watch before ordering a replacement. The CMM.10 has 19 mm lugs, but compatibility with that strap size is not established for the Forces Sous-Marines edition.
How does it fit into the Navygraf range?
The Navygraf name connects the Forces Sous-Marines watch, as described in the listing, with Yema’s broader dive-watch family. The currently documented Marine Nationale variants offer useful points of comparison, but not a specification sheet for this unidentified edition. To compare verified Navygrafs, check caliber, case dimensions, water resistance, crystal and bezel materials, included strap or bracelet, warranty and the price for your region. Keep the Forces Sous-Marines watch separate from that comparison until its reference is confirmed.
