AUDEMARS PIGUET ROYAL OAK TOURBILLON EXTRA-THIN OPENWORKED WATCH
Having crafted their first openworked timepiece in the 1920s, Audemars Piguet has had a long time to perfect the art — almost as long as it takes to say the full name of theAudemars Piguet Royal Oak Tourbillon Extra-Thin Openworked Watch. Now available in yellow gold in addition to platinum, it’s powered by a highly-visible, hand-finished movement with a 70-hour power reserve, placed in vertical alignment with the tourbillion. Measuring 41mm across, the case is slightly thicker than the 4.46mm movement, and comes attached to a matching yellow gold bracelet.
PRICE: $241,000 (You can purchase he Royal Oak Tourbillon Extra-Thin Openworked Watch here)
