An openworking or skeleton-working specialist for almost half a century, Armin Strom has given his eponymous brand a solid reputation as well as the tools to ensure vertical integration of production on the one hand, and on the other the enduring success of his company  beyond its founding watchmaker. Building on this independence, the Manufacture Armin Strom is now part of the circle of talented small manufacturers that are well worth discovering. In the wake of its first tourbillon calibre made in-house last year, the Tourbillon Water stands out from other models in this segment. In addition to the sophisticated and immediately identifiable aesthetic of the exterior highlighting the precious mechanism within, the new Tourbillon ATC11 calibre is distinguished by an 18K white gold lever and an assembly within which the balance and the seconds pinions are positioned on the same axis. The mainplate and tourbillon bridge are adorned with exquisitely finished decoration. Its twin barrel ensures a ten-day power reserve. Armin Strom has developed modern openworking methods by integrating his designs right from the first stages of movement making, before producing then entirely in-house. Fans will doubtless wish to acquire the entire Tourbillon Armin collection inspired by the four elements : Earth, Fire, Water and Air.
