Experience the craft of Armin Strom in the Skeleton (ref. ST15-PE.40), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 43.4 mm in diameter, with a thickness of 13 mm, defined by a round silhouette, protected by pvd coating. The caseback is open, and the crystal is sapphire, delivering water resistance to 5000 meters. At a glance, the dial balances texture and clarity: a skeleton tone, framed by stick / dot hour markers, and dauphine hands. At its heart beats a proven engine: the ARM09-S Pure caliber. Issued as a limited edition, appealing to focused collectors. Introduced in 2014. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
