The openworked architecture foregoes the traditional dial entirely, allowing the deep blue PVD coated mainplate to serve as a visual centerpiece. The watch explores contrast in form and finish, highlighting the depth and clarity of its mechanical design.

Crafted to perform, designed to endure

Powering the watch is the manual-winding Calibre ARM21, entirely developed, decorated and assembled in-house.

With two barrels mounted in series, it delivers a full seven-day power reserve and a beat rate of 3.5 Hz ensures enhanced chronometric stability.

A signature feature is the three-dimensional power reserve indicator, driven by a conical gear and polished cone, a kinetic reference to traditional pocket watches.

The movement reveals its choreography in real time: the ratchet wheels turning, barrels unwinding and gear train pulsing, all arranged in symmetrical harmony.

Finishing is the final statement

Like all Armin Strom creations, from the purest to the most complex, the One Week is a masterclass in haute horlogerie hand-decoration.
