Model History
The Skeleton Pure collection was born in 2009, right after the opening of the new Bienne manufacture and the development of the first fully in-house calibre, the ARM09. The model represents the modern evolution of Armin Strom's founding craft: the house presented its first skeletonized watch in 1983, and in 1991 the founder earned a Guinness World Record for the smallest hand-skeletonized women's watch in the world.
The Skeleton Pure's philosophy is a deliberate contrast: pairing a skeletonized high-watchmaking movement, entirely developed and hand-finished in-house, with the aesthetics and proportions of a sports watch. In the "Air" execution this contrast is heightened with a brushed grade 5 titanium case — a material that, unlike cheaper titanium grades, still allows for mirror-polished bevels.
The hand-wound ARM09-S calibre, with two barrels visible in series, offers a power reserve of a full 8 days — a figure achieved precisely thanks to the two barrels, uncommon among manufacture skeleton watches — with hand-beveled and polished bridges and wheels standing out against the matte anthracite-grey main plate, in sharp chromatic contrast with the mirror-finished parts.

Main Executions
The founder's 1991 Guinness World Record for the smallest hand-skeletonized women's watch in the world isn't an isolated anecdote: it's proof that skeletonization, for Armin Strom, was never a simple aesthetic touch applied to an existing movement, but a genuine artisanal discipline cultivated for decades before the brand even developed its own calibres.
