Yema Watch: Navygraf Meteorite CMM.10 Black 39 mm

Yema Navygraf Black Meteorite: a titanium diver with a dial from space

A meteorite dial in a true diving watch: the Yema Navygraf Black Meteorite CMM.10, reference 22.26.10.66.TNL.M, combines a unique material with a construction designed to be worn. This black version belongs to the Navygraf collection and stands out for its Muonionalusta meteorite dial, whose crystalline patterns make every piece unique.

The black dial highlights the silver lines of the meteorite and extends the shade of the bezel. The ensemble remains understated at first glance, then reveals its texture as the light changes. The 39 mm Grade 2 titanium case, 46 mm lug-to-lug and 11 mm thick, maintains modest proportions. A double-domed sapphire crystal protects the dial; the applied indices and hands feature Grade A BGW9 Super-LumiNova with blue emission to assist with reading in the dark.

Inside, the French-manufactured CMM.10 automatic caliber simply displays the hours, minutes, and seconds, with no date. Its 70-hour power reserve allows you to set the watch aside for a weekend without needing to wind it immediately. Beating at 28,800 vibrations per hour, it offers an accuracy of -3 to +5 seconds per day. The transparent sapphire case back allows its operation to be observed.

The matching titanium bracelet keeps the entire piece light, and its folding clasp with quick micro-adjustment facilitates wrist fitting. With its screw-down crown, 120-click unidirectional bezel, and 300-meter water resistance, the Navygraf retains its identity as a diver. This edition is limited to 150 numbered pieces, delivered with a certificate of authenticity for the dial and a five-year international warranty.

Why choose this watch?

For the dial, primarily. The Muonionalusta meteorite and its unique natural patterns give this Navygraf an identity that goes beyond mere color. The photographs illustrate the model; the crystalline pattern of your specific piece will be different.

For its proportions and equipment, second. The Grade 2 titanium and the 39 mm diameter combine lightness with controlled presence. The bracelet's quick micro-adjustment provides a practical advantage when wrist size varies throughout the day.

Finally, this edition retains the qualities of a sports watch: 300 meters of water resistance, a diving bezel, and an automatic movement offering a 70-hour power reserve. It is intended for those looking for a French mechanical diver with a singular dial, without an abundance of extra functions.

About the Yema brand

Founded in 1948, Yema occupies a special place in French watchmaking. Its diving watches, aviation watches, and chronographs have built an identity focused on instruments and their applications.

Now based in Morteau, the company develops its Manufacture calibers. For the CMM.10, the design, machining of the bridges and plates, assembly, and regulation are part of a Franco-Swiss ecosystem in the Jura Arc. This organization bridges local expertise and specialized watch components.

The Navygraf expresses the marine side of this history. The Meteorite version continues this approach with a titanium construction and a natural dial, to be discovered among our selection of Yema watches at PAUSE, in Toulouse.
