US customers, please contact the sales team.
The One Week Manufacture Edition Blue reinterprets Armin Strom’s foundational calibre with a new captivating identity. Housed in a 41 mm stainless steel case and paired with an integrated steel bracelet, the timepiece balances ergonomic performance with sculptural design. 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.
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.
Like all Armin Strom creations, from the purest to the most complex, the One Week is a masterclass in haute horlogerie hand-decoration. Straight and circular grained surfaces, chamfered and polished bevels, Geneva stripes, polished screws and sinks have been applied by expert hands. Each movement is assembled twice – ensuring every piece meets the highest standards of both performance and aesthetics.
With only 100 pieces available, this edition continues Armin Strom’s pursuit of mechanical innovation.
