From the cosmos to your wrist
I expected the meteorite to be the first thing I noticed. What surprised me was how little it announced itself. From certain angles, the darker YEMA Navygraf Meteorite CMM.10 looks almost like a straightforward black-dial diver. Turn your wrist, and the surface shifts towards grey, revealing lighter striations that were barely visible a moment earlier. It is a lovely effect, and considerably more subtle than I had anticipated.
We had reference 22.26.10.66.TNL.M in for review. Having seen numerous meteorite dials over the past five years, I think this one might be my favourite. That probably says as much about my taste in dive watches as it does about meteorites. I like a dial I can read without having to negotiate with it. Here, the texture gives you something to enjoy when you look closer, while leaving the basic business of telling the time alone.

Key features of the YEMA Navygraf Meteorite CMM.10 Limited Edition
A little less meteorite drama
Meteorite can be a busy material. Those intersecting bands are fascinating, but depending on their contrast and the design around them, they can compete with the hands and markers. I have certainly seen examples where the dial becomes the whole conversation.
The darker Navygraf avoids that problem. Its pattern moves in and out of view with the light, and the familiar dive-watch layout remains easy to read. Round hour plots alternate with arrow-shaped markers at the cardinal points. The polished applied markers and hands provide definition against the darker surface. As far as a dive watch goes, it does not get much more quintessential than this.
The matte black bezel is a particularly good match. It keeps the surrounding surfaces subdued and gives the meteorite room to show its finer details. The insert is black stainless steel, with a fully graduated 60-minute scale, and the unidirectional bezel has 120 clicks. YEMA applies Grade A BGW9 Super-LumiNova to the bezel markings, as well as the hour markers and all three hands. The lume is strong, and the dial’s clarity carries through after dark.
There is a good story behind the material, too. YEMA uses Muonionalusta meteorite, whose fragments have been recovered in northern Sweden. The first known fragment was discovered in 1906. The iron-and-nickel material is around 4.5 billion years old, and its characteristic Widmanstätten pattern formed as it cooled exceptionally slowly within its parent body. Different cuts reveal different arrangements of those crystalline bands, so each dial has its own pattern.
That is plenty of history to fit beneath a sapphire crystal. Fortunately, you can appreciate this watch without giving anyone a lecture about the early solar system.
The proportions do a lot of the work
The case measures 39mm across, 46mm from lug to lug, and 11mm thick. Those last two numbers deserve particular attention. On wrist, the restrained length is a dream, and the slim profile makes the Navygraf an easy watch to live with. There is very little sense of the height or overhang that can make some divers feel cumbersome.
Grade 2 titanium suits these proportions nicely. Its low weight helps keep the watch comfortable, particularly with the matching bracelet. Vertical brushing gives the case a practical finish, while mirror-polished bevels along the lugs bring a little definition to the edges. A 2.20mm double-domed sapphire crystal completes the profile.
Our recent Superman Bronze CMM.10 review looked at another 39mm YEMA diver; that watch measures 48mm from lug to lug. The Navygraf trims that span by 2mm. It is a small difference on paper, but the compact footprint is one of the strongest arguments for this watch.
A welcome clasp upgrade
The titanium H-link bracelet feels solid, and the ratcheting clasp is a big improvement over earlier models. A bracelet can have all the right proportions and still be frustrating if you cannot find a comfortable fit. The additional adjustment here makes a welcome difference to the overall package.
The links use push pins. I would also flag the 19mm lug width, which remains a slightly awkward choice for anyone who likes swapping straps. There are options available, of course, but a more conventional 20mm opening would make life easier. It is a modest quibble on a watch whose supplied bracelet works well.
A reason to turn it over
The sapphire exhibition caseback gives you a great view of YEMA’s automatic CMM.10. The manufacture calibre runs at 28,800 vibrations per hour and offers a 70-hour power reserve. YEMA quotes accuracy of −3/+5 seconds per day; that is the brand’s stated performance, rather than a timing result from this review.
Seventy hours is useful breathing room if you rotate through a few watches. It also gives the Navygraf a practical specification to accompany the unusual dial. The titanium caseback surround carries the individual limited-edition number and the watch’s serial number.
We have been following YEMA’s movement development across several collections, including the micro-rotor-equipped Granvelle Renaissance CMM.29. The Navygraf brings that manufacture focus back to familiar tool-watch territory. For me, being able to see the CMM.10 adds to the pleasure of owning something like this. There is a worthwhile view on both sides.

Final thoughts
The darker meteorite dial is what stays with me. I like that it can look almost black at one angle and reveal those fine grey striations at another. Paired with the matte bezel, it gives the Navygraf a surface I would happily keep looking at.
The dimensions, strong lume, and improved clasp support that first impression. This is an easy diver to appreciate on the wrist, with a few interesting details waiting for a closer look. The 19mm lugs are mildly inconvenient, but they do little to temper my enthusiasm. It is an excellent addition to the Navygraf collection, and the darker reference would be my pick.
