Audemars Piguet‘s Royal Oak family of watches — named for the British Royal Navy battleships — is widely recognizable for its strongbox case, octagonal bezel and “Tapisserie” motifs. Diving deeper, its Offshore line takes on the spirit of innovation through the continual use of high-tech materials and functional upgrades. Its latest edition, the Selfwinding Tourbillon Chronograph, deviates from the traditional hand-winding mechanisms we’re used to seeing in the Tourbillon Chronograph collection and opts for an automatic mechanical AP caliber 2897. Additional details include a 44mm x 14mm forged carbon case, a black ceramic bezel, a “Méga Tapisserie” dial, titanium push-piece guards, a platinum rotor, and a black rubber strap. Limited to just 50 units, the Audemars Piguet Royal Oak Offshore Selfwinding Tourbillon Chronograph will sport a price tag that will hover around $285,600 USD.
