Audemars Piguet PIGUET-2601

The Audemars Piguet caliber 2601 is a Swiss-made quartz movement featuring 321 jewels and powered by a type 321 battery that provides approximately 36 months of operation. Time adjustment is performed via a pusher located on the crown or case back: a quick press advances the minute hand by one minute, a press lasting two to four seconds advances the hour hand, and a prolonged press enables continuous forward motion. This caliber is notably used in ladies-size Royal Oak models.
