Yema applies a slice of Muonionalusta meteorite to a 39mm titanium Navygraf, pairs it with the in-house CMM.10 movement and a titanium bracelet, and limits production to 150 individually numbered pieces in black or green.
Each dial uses Muonionalusta meteorite, revealing unique Widmanstätten patterns when cut and polished.
Case is 39mm titanium, 11mm thick, 300m water resistance, and fitted with a 2.2mm double-domed sapphire crystal.
Movement is Yema’s manufacture CMM.10: 28,800vph, 70-hour power reserve, -3/+5 s/day accuracy specification.
Yema's Navygraf Meteorite CMM.10 is a limited-edition dive watch that places a real slice of Muonionalusta meteorite at the center of the dial. The meteorite's iron-and-nickel structure produces Widmanstätten patterns when cut and polished, so each dial shows a distinct, changing texture as light moves across it. The model is offered in two dial finishes — black or green — and limited to 150 individually numbered pieces.
A 2.2mm double-domed sapphire crystal echoes the curved profile of vintage crystals and protects the meteorite dial. The display caseback uses sapphire to expose the CMM.10 movement and a circularly brushed titanium surround that carries each watch's limited-edition and serial numbers. Water resistance is rated at 300 meters.
The meteorite dial is available in black or green and shows Widmanstätten patterning that becomes more or less apparent depending on lighting. Applied hour markers and hands are polished and filled with Grade A BGW9 Super-LumiNova, which emits a blue glow in the dark. A white minutes/seconds track circles the dial's edge to assist precise reading.
The watch runs on Yema's CMM.10 manufacture calibre. Technical highlights provided by Yema include an operating frequency of 28,800 vph, a 70-hour power reserve supported by a large barrel, and a chronometric specification of -3/+5 seconds per day. The movement features a transversal bridge, Glucydur balance wheel, non-magnetic alloys, Incabloc shock absorbers, and a unidirectional rotor on ball bearings. The display caseback lets owners see the movement's finishing and layout.
The Meteorite CMM.10 comes on a vertically brushed titanium bracelet that matches the case finish. It measures 19mm at the lugs and closes with a folding clasp that offers micro-adjustment for fit. The overall dimensions and bracelet choice place the watch in a comfortable, sport-oriented size suitable for daily wear and diving.
Production is capped at 150 individually numbered pieces. Yema prices the Navygraf Meteorite CMM.10 at EUR 2,900 or USD 3,350. Reference numbers differ by dial color: one for the black dial and one for the green dial.
How this fits within the Navygraf line
Yema has been expanding the Navygraf beyond conventional tool-watch materials, previously experimenting with forged carbon and mother-of-pearl. This Meteorite edition continues that exploration by introducing a very old natural material — Muonionalusta — and combining it with a titanium case and the brand's in-house movement, aiming to add uniqueness while maintaining dive-watch capability.
Delma’s Midland collection is the brand’s sporty-chic take on the integrated-bracelet watch, bringing some 1980s flavour to the category. The watches in this collection come in two sizes, 40mm and 34mm, with the automatic 40mm versions sitting at an accessible price point of around EUR 1,400. We have already seen the M
Astronomy is part of Louis Moinet‘s history, who created the “compteur de tierces” chronograph specifically for celestial observations. The brand bearing his name has kept the connection alive through its multiple space-themed creations, such as the Super Moon and Mars Mission, the Space One Chronograph, the more recen
Mechanical watches have accompanied astronauts and cosmonauts into space for decades, but few contemporary watches can claim to have been developed specifically around the demands of extravehicular activity, like Konstantin Chaykin’s new SC02C.
