YEMA puts a 4.5-billion-year-old meteorite on the Navygraf’s dial

YEMA’s latest Navygraf carries a tiny piece of deep space on the wrist. Its dial is cut from genuine Muonionalusta meteorite, an iron-nickel material that formed around 4.5 billion years ago. Slow cooling created the distinctive Widmanstätten crystalline lattice: intersecting bands that give every finished dial its own unrepeatable pattern.

The meteorite is thought to have fallen in northern Scandinavia roughly one million years ago. Its dramatic natural geometry is the centrepiece here, framed by bold luminous markers and the familiar rotating dive bezel. YEMA says this marks the first Navygraf with both a meteorite dial and an entirely titanium case and bracelet.

Grade 2 titanium keeps the 39mm case lightweight, with an 11mm thickness, double-domed sapphire crystal and 300 metres of water resistance. Inside, the French-made automatic CMM.10 calibre runs at 4Hz, with a stated 70-hour power reserve and chronometric performance rated at -3/+5 seconds per day. The display back reveals the movement without sacrificing its dive rating.

Just 150 individually numbered examples are planned. Each includes a certificate documenting the meteorite dial’s provenance. YEMA lists the edition at US$3,350 on its US storefront, with shipping expected at the end of October 2026. It is an unusual combination: extraterrestrial raw material, restrained utilitarian proportions and modern French manufacture watchmaking.
