Audemars Piguet Frosted Gold Double Balance Wheel Openworked

Audemars Piguet's Royal Oak Double Balance Wheel Openworked, reference 15412BA.YG.1224BA.01-B, measures 41 mm across in 18-carat yellow gold with a frosted finish. The case stands 10.1 mm thick and carries a sapphire crystal over the openworked dial. Inside is the self-winding calibre 3132, its bridges and mainplate skeletonized so the double balance wheel construction is visible from the front. Central seconds runs off the same movement. The bracelet is hammered 18-carat yellow gold, matching the case, and closes with an AP folding clasp. Water resistance is rated to 50 metres, modest for daily wear but standard for this line.
