Chronoswiss C672

The Chronoswiss C.672 is a hand-wound mechanical movement based on the ETA 6497-1, modified in-house with a hacking stop lever and swan neck regulator. Measuring 36.6mm in diameter and 5.4mm thick, it beats at 18,000 vph with 18 jewels and Incabloc shock protection. The movement converts the base caliber's small seconds subdial at 9:00 to a central sweeping seconds hand, an indirect configuration that can occasionally produce a slightly stuttered hand motion. It powers the Chronoswiss Timemaster.
