Swiss watch Manufacture ARMIN STROM joins the highly exclusive club of horologers that develop and produce their own tourbillon movements.

The tourbillon of the new ATC11 calibre is distinguished by a lever worked in 18ct white gold and an assembly that places the balance wheel and seconds pinion on the same axis.


A hallmark of the Tourbillon Collection is the exposed, intricate inner mechanics. The brand has promoted modern forms of skeletonising, with designs integrated from the early stages of the calibre before being entirely crafted in the Manufacture.

The ARMIN Tourbillon Collection, based on the elements Earth, Fire, Water and Air present the brand’s aesthetic genius and pays testament to the Manufacture’s full spectrum of watchmaking skills.
