Audemars Piguet Royal Oak Double Balance Wheel Open-worked 37mm

The new 37mm Royal Oak Double Balance Wheel Open-worked watch for women features caliber 3132, first introduced in 2016 in the 41mm Royal Oak case. By incorporating two balance wheels and two hairsprings that are assembled on the same axis, the system oscillates in pure harmony.

This patented mechanism involves a complex fabrication procedure that improves precision and stability, while allowing the beating heart of the watch to be visible from both sides of the case. The movement is rhodium plated to softly highlight the golden regulating organ and the upper balance bridge.

The indexes and hands match perfectly this refined set. Additionally, all the finishing operations on the bridges and main-plate are done by hand: beveling, chamfering, polishing, satin-brushing and circular satin-brushing.

The Royal Oak Double Balance Wheel Openworked is available in Hammered 18-carat white gold and pink gold versions with open-worked rhodium-toned dial.
