In-House Watch Calibres Developed by Armin Strom

Every movement that comes from our manufacture is a statement of independence. We develop, design and produce our in-house watch calibres – from the main plate to the balance wheel, from gear trains to the escapement. And, of course, we hand-finish them. Only hairsprings and jewels are sourced from specialised Swiss suppliers.

That’s because, as scientists of movement, we know when not to reinvent the wheel. Our calibres range from refined manual-winding movements to sophisticated automatic ones, from single-barrel to double-barrel configurations and from our patented resonance system to intricate minute repeater mechanisms.

You could say we’re movement nerds. And that would make us proud.
