At its heart is Muonionalusta meteorite, a material formed approximately 4.56 billion years ago in the earliest days of our solar system. Older than Earth itself, it journeyed through space for billions of years before reaching northern Scandinavia, where fragments were ultimately discovered in present-day Sweden.

Composed primarily of iron and nickel, Muonionalusta reveals a distinctive crystalline structure known as the Widmanstätten pattern, a natural formation created through extraordinarily slow cooling over millions of years. No two sections are alike, making every dial inherently unique.

Polished Breguet numerals rise above this ancient celestial material, while applied chapter rings and refined minute and seconds markers bring clarity and balance to the composition. The result is a dial that is both deeply historic and unmistakably contemporary.

Beneath the dial lies our hand-engraved mechanical caliber, crafted using traditional techniques and finished with the same attention to detail that defines every Mount Vernon. The juxtaposition of a material forged before the formation of our planet with the enduring craft of mechanical watchmaking creates a timepiece unlike any other.

Among the oldest materials one can wear on the wrist, the Mount Vernon Meteorite is a rare meeting of cosmic history, artisanal craftsmanship, and mechanical refinement.
