Moritz Grossmann Caliber 100.0

Caliber 100.0 is a manual-winding movement manufactured by Moritz Grossmann. It contains 188 parts and 17 jewels, with the jewels set in gold chatons featuring clear sapphires. The movement operates at 18,000 vph and delivers a 42-hour power reserve. Technical construction employs a pillar architecture with a 2/3 plate, and the balance cock is hand-engraved with a micrometer screw. The caliber is in production and serves as the base movement for the 100 Series, featuring a power reserve indicator.
