Audemars Piguet Double Balance Wheel Openworked

Audemars Piguet's Royal Oak Double Balance Wheel Openworked, reference 15407BA.OO.1220BA.01, has a 41mm case in 18-carat yellow gold. The case measures 9.9mm thick. A sapphire crystal covers the openworked dial, which exposes the skeletonized movement and its two balance wheels. The self-winding calibre 3132 drives the watch, with central seconds among its functions. The construction lets light pass through the blackened bridges and mainplate, so the mechanics are visible from both sides. A yellow gold bracelet with an AP folding clasp completes the piece. Water resistance is set at 50 metres.
