FAQ
Is the Navygraf Marine Nationale CMM.10 automatic or quartz?
The Navygraf Marine Nationale CMM.10 is automatic. The Yema CMM.10 winds itself from the motion of your wrist, so it needs no battery. A full wind holds roughly 70 hours, so it keeps running overnight off the wrist; left longer it stops and restarts once you wear or hand-wind it.
What movement does the Navygraf Marine Nationale CMM.10 use?
The Navygraf Marine Nationale CMM.10 is powered by the Yema CMM.10 from Yema, an automatic caliber with 27 jewels, a 70-hour power reserve, and a 28,800 bph beat rate. Being automatic, it winds from the motion of your wrist and needs no battery.
Does the Navygraf Marine Nationale CMM.10 have a date?
No — the Navygraf Marine Nationale CMM.10 has no date display. Some movements in this class can drive a date, but this one is specced without it, leaving a cleaner, more symmetrical dial. If a date is essential, look for a dated variant or a different model.
How water resistant is the Navygraf Marine Nationale CMM.10?
The Navygraf Marine Nationale CMM.10 is rated to 300 m. That is a high water-resistance rating: comfortable for swimming, snorkelling and recreational diving, with margin to spare for everyday wear. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.
