Audemars Piguet Royal Oak Concept Flying Tourbillon GMT Watch
As the Royal Oak turns 50, the Concept line celebrates its 20th anniversary. Audemars Piguet marks the occasion with a brand new model. The Royal Oak Concept Flying Tourbillon GMT Watch is based around a 44mm sandblasted titanium case. It's topped with a green ceramic bezel and features a skeletonized dial with black PVD-treated bridges, pink gold details, and green CVD-coloured inserts, while an AP caliber 2954 movement boasting an impressive 237-hour reserve powers the piece and its tourbillon function. Sold in very limited quantities, the travel watch is finished with a textured green rubber strap, echoing its verdant hue, and includes an interchangeable rubber strap.
