Before the Earth was fully formed, the material now embedded in the Navygraf Meteorite CMM.10 was already cooling in space. The Muonionalusta, one of the oldest known meteorites, formed approximately 4.5 billion years ago in the metallic core of a proto-planet.

Limited to 150 individually numbered timepieces, the Navygraf Meteorite CMM.10 pairs a dial crafted from this ancient material with a 39mm titanium case and its matching bracelet.

Titanium provides lightness and corrosion resistance, while the Muonionalusta offers a natural crystalline pattern formed during the meteorite's cooling over millions of years in space. This pattern varies throughout the meteorite, making each dial a unique piece.

A METEORITIC PATTERN IMPOSSIBLE TO REPLICATE

Deep within its ancient parent body, iron and nickel cooled and crystallized over the course of millions of years. This exceptionally slow process created the Widmanstätten structure, a geometric lattice of crystalline bands that no furnace on Earth can replicate on the same scale. The structure is a natural testament to the extraterrestrial origin of the Muonionalusta.

Cut and polished, the Muonionalusta fully reveals the Widmanstätten pattern, the characteristic that makes this meteorite so prized in watchmaking. Its crystalline bands vary in density and direction throughout the material, appearing finer in some areas and wider in others. No two finished dials share the same arrangement of crystalline lines.

As you move your wrist, the light catches different parts of the lattice, causing the pattern to shift from subtle to striking. The applied hour indices and polished hands create a sharp contrast against this iridescent surface, preserving the immediate legibility of the Navygraf.

Each dial is a fingerprint that took four and a half billion years to form, unique to the watch that houses it.

 

 

MUONIONALUSTA: A MILLION YEARS IN THE ARCTIC

The Muonionalusta takes its name from a location on the Muonio River in Swedish Lapland, approximately 140 kilometers north of the Arctic Circle. The meteorite is believed to have fallen in northern Scandinavia about a million years ago, where its fragments survived successive ice ages.

The first known fragment was discovered by chance in 1906 near the village of Kitkiöjärvi. Since then, other fragments have been recovered across an area of about 25 by 15 kilometers, near the border between Sweden and Finland.

Searching in this remote territory is dictated by the seasons. Winter snow and darkness prevent searches for most of the year, leaving the brief Arctic summer as the most realistic opportunity for recovery. Even then, the wet terrain and isolation make every search difficult.

This history is part of what you are wearing: a material formed beyond the borders of Earth, having survived successive ice ages and recovered from the Swedish Arctic nearly a million years after its arrival.
