SIGNED AUDEMARS PIGUET, ROYAL OAK TOURBILLON CHRONOGRAPH MODEL, REF. 25977ST, CASE NO. F71407, CIRCA 2010

Launched in 2003 and produced until 2013 in very small numbers, the present Audemars Piguet Royal Oak reference 25977ST is an impressive, stately, and mechanically complicated timepiece.

The watch measure 44mm and has been entirely crafted in stainless steel, including its bracelet. Reference 25977ST features a chronograph and tourbillon which happens to be visible at the bottom register of the black Tapisserie dial. On the rear, a sapphire caseback allows for one to view caliber in-house caliber 2889 featuring Côtes de Genève, anglage beveling, and mirror-polished screw heads all finished to the highest degree.
