The Audemars Piguet Royal Oak Offshore Chronograph reference 26470ST.OO.A027CA.01, often nicknamed the Navy, is a prominent luxury sports watch featuring a 42mm stainless steel case. This model is characterized by its octagonal bezel secured by eight hexagonal screws and a blue Mega Tapisserie dial. The dial is adorned with Arabic numerals, silver-toned sub-dials, and vibrant orange accents on the chronograph hands and inner tachymeter scale. It is equipped with a scratch-resistant sapphire crystal and a transparent caseback that reveals the intricate movement within. The timepiece is traditionally paired with a blue vulcanized rubber strap featuring a stainless steel pin buckle.
Powering the watch is the self-winding caliber 3126/3840, which consists of an in-house base movement and a specialized chronograph module. This automatic movement provides a power reserve of approximately 50 hours and operates at a frequency of 3Hz. In terms of complications, the watch includes a central chronograph seconds hand, 30-minute and 12-hour counters, and a date window positioned at 3 o’clock. The case is designed with a screw-down crown and pushers to ensure water resistance up to 100 meters, making it suitable for light swimming.
General reviews of this reference highlight its bold aesthetic and exceptional finishing, often noting the high quality of the brushed and polished surfaces. While its 42mm diameter and 14.6mm thickness give it a substantial wrist presence, some enthusiasts observe that the integrated lug design causes it to wear larger than its dimensions suggest. Critics occasionally point to the legibility challenges of the deep-set date window and the use of a modular rather than a fully integrated chronograph movement at its price point. Nevertheless, it remains a highly regarded icon within the Offshore collection for its striking color palette and robust construction.
