1142 QP

Caliber 1142 QP is an internally developed movement succeeding the 1141 QP, powering a perpetual calendar with date, day, month, leap year, and moon phase displays, alongside a chronograph with a 30-minute counter and direct-drive seconds. It requires no calendar adjustments until March 1, 2100, and meets the rigorous Hallmark of Geneva standards, visible through a sapphire caseback. Chronograph: Column wheel chronograph.
