Double Open-Ratcheting 180-Year Revival | Czapek Returns to its Roots 2026 Novelty

When looking at the back of a mechanical watch, there's a prominent large gear that catches the eye. This is commonly referred to as the "barrel wheel" or "ratchet wheel," a crucial component for winding the mainspring.

CZAPEK's hand-wound movement "SXH1" features a "double open ratchet," with two of these ratchet wheels arranged side-by-side.

It's not merely decorative. It's a structure emblematic of CZAPEK, combining the function of driving the watch, a power reserve of approximately 7 days, and a design inherited from the 19th century.
