Audemars Piguet Royal Oak Offshore Chronograph Perpetual Calendar watch

The Audemars Piguet watch design has served as the basis for a variety of exciting mechanical complications.

The Royal Oak Offshore Chronograph Perpetual Calendar watch first of all offers a chronograph feature which is capable of measuring time intervals within 30 minutes or up to 12 hours with precision to within 1/8 of a second; however what makes this watch truly remarkable is its perpetual calendar mechanism, which indicates day of the week, date, month, moonphases, and leap year, automatically adjusting to account for months of less than 31 days, and the month of February in particular (the month critically affected by the leap year cycle). Audemars Piguet has fitted the Royal Oak Offshore Perpetual Calendar Chronograph watch with a fine selfwinding movement. Based upon the excellent Jaeger-LeCoultre 889 Caliber, which has been considerably modified by Audemars Piguet, this movement demonstrates excellent reliability and winding efficiency, as well as traditional watchmaking craft. The mainplate of the movement is adorned with perlage circular graining, while the bridges show off Cotes de Geneve (striping) and edges which have been finely chamfered. The centrally mounted rotor, gilt engraved with the technical specifications and the brand signature, displays Cotes de Geneve finishing, and also a mass-enhancing peripheral sector in 21K gold.

The Audemars Piguet Royal Oak Offshore Perpetual Calendar Chronograph watch features a case and bracelet made from titanium, stainless steel, or 18K gold. This intricate design, which features many dozens of intricate facets and contrasts between brushed and polished surfaces demands extensive hand finishing, and is a true masterpiece of luxurious craftsmanship. The eight sided bezel, vertically brushed on top, and polished on its sides, displays the hexagonal screws that characterize the Royal Oak watch design; the slots of these iconic screws are aligned to form a circle around the dial, which is decorated with an intricate "Grand Tapisserie" pattern and polished gold hour markers and hands which have been filled with luminous material.

Despite its exquisite complicated movement and unsurpassed finish, the Audemars Piguet Royal Oak Offshore Perpetual Calendar Chronograph watch is truly sports capable, its sealed case with rubber coated crown and pushers ensuring water-resistance to a depth of 100 meters. Also of note, a soft-iron inner shield covers the movement, protecting it against the ravages of magnetic fields. To ensure that the Royal Oak Offshore Perpetual Calendar Chronograph watch stays securely fastened to its owners wrist during any activity, Audemars Piguet has equipped the bracelet with a double sided deployant clasp that has an additional folding clasp for added confidence.
