The One Week Skeleton Rose Gold is a tribute to the skeletonisation work of Armin Strom, who founded the company in 1967.
Armin Strom today introduces the One Week Skeleton Rose Gold at Dubai Watch Week 2025, limited to 50 pieces. For the first time, the in-house calibre sits in a solid 18-carat rose gold case.
The movement is now fully skeletonised, with rose gold coloured finger bridges, hands and indexes set against a black textile strap. The hand-wound Calibre ARM21 reinterprets the brand’s first in-house calibre, the ARM09. Two barrels in series, wound by two ratchet wheels on the dial side, give seven days of power reserve.
A conical power reserve mechanism, inspired by historical pocket watches, works with a three-dimensional indicator. Every component is decorated by hand, and Armin Strom assembles each One Week twice.
It is a tribute that hides nothing: every wheel, screw and spring stays in view.
