Description
Yema has put a slice of the Muonionalusta meteorite into its Navygraf diver, wrapped it in grade 5 titanium, and asked €2,900 for it. That is the whole pitch, and it is a very good one: a genuine meteorite dial, a 300m case, and a French manufacture calibre with 70 hours of running time, at a price where most brands are still fitting a Sellita and calling it a day.
Two references make up the launch — 22.26.10.66.TNL.M with a black meteorite dial and 22.26.10.64.TNL.M with a green one — and each is limited to 150 individually numbered pieces. Muonionalusta is the iron meteorite recovered in northern Sweden, roughly a million years in the ground, and when it is sliced and acid-etched it reveals the Widmanstätten pattern: a crystalline lattice that cannot be faked and that no two dials share.
Design
The case is 39mm across, 11mm thick and 46mm lug to lug, in titanium finished with vertical brushing on the flanks and mirror-polished bevels running the length of the lugs. It is a restrained set of proportions for a 300m diver, and titanium keeps the weight down further. The bezel is a 120-click unidirectional unit with a black stainless-steel insert carrying a 0–60 minute scale and a luminous triangle at 12. Above the dial sits a 2.2mm double-domed sapphire; the caseback is a sapphire display window ringed in circularly brushed titanium.
The dial is the reason to buy the watch. The meteorite is finished black or green, the Widmanstätten lattice reading as a fine crosshatch that shifts with the light, and Yema has kept everything on top of it deliberately plain: applied polished hour markers filled with Grade A BGW9 Super-LumiNova, luminous hands glowing blue, a white minute track around the periphery. The bracelet is vertically brushed titanium on a folding clasp with a micro-adjustment system.

What's Exciting
The CMM.10 is what makes this more than a novelty dial. Yema built the calibre at its own Morteau facility, and the specification is not a marketing exercise: 70 hours of power reserve, a Glucydur balance on a transversal bridge, Incabloc protection, hacking seconds, and a stated -3/+5 seconds a day that sits inside chronometer tolerance without paying for the certificate. Finding a genuinely in-house European movement of that quality under €3,000 is close to impossible, and Yema has been quietly doing it for several years while the conversation stayed fixed on Swiss ebauches.
Put the meteorite dial on top and the value argument gets harder to argue with. Meteorite dials are normally a five-figure proposition — the material is awkward to cut, brittle to work and priced by rarity — and they usually arrive attached to a precious-metal case. Here it comes with titanium, 300m of water resistance and a bezel you can actually use. At 150 pieces per colour this will not sit around, and at €2,900 it probably should not.
History
Yema was founded in Besançon in 1948 and spent its first decades as one of France's most prolific tool-watch makers, supplying divers and chronographs to the French navy and air force. The Navygraf line is the diving side of that history, and in recent years Yema has been widening it out — forged carbon and mother-of-pearl dials among the experiments — rather than treating it strictly as a hardware-store diver.
The CMM.10 belongs to the brand's return to making its own movements, produced at Morteau in the Doubs, close to the Swiss border and to the region's long watchmaking tradition. That vertical integration is what lets a 39mm titanium diver with a meteorite dial land under €3,000; a brand buying its calibres in could not reach that number with the same specification.
