The Audemars Piguet Royal Oak Offshore Selfwinding Chronograph reference 26231ST.ZZ.D038CA.01 is a 37mm luxury sports watch featuring a stainless steel case with a thickness of approximately 12.4mm. This model is distinguished by its vibrant green dial adorned with a Lady Tapisserie pattern, which is framed by a stainless steel bezel set with 32 brilliant-cut diamonds totaling roughly 1.02 carats. The case construction includes a screw-locked crown and a solid case back, ensuring water resistance up to 50 meters. It is paired with a matching green rubber strap and an AP folding clasp, and the package often includes an additional blue rubber strap for versatility.
The timepiece is powered by the manufacture Calibre 2385, a self-winding mechanical movement composed of 304 parts and 37 jewels. This high-performance movement operates at a frequency of 21,600 vibrations per hour and provides a power reserve of approximately 40 hours. In terms of complications, the watch features a column-wheel chronograph with a 30-minute counter at 3 o’clock and a 12-hour counter at 9 o’clock. Additional functions include central hours and minutes, small seconds at the 6 o’clock position, and a date display positioned between 4 and 5 o’clock.
General reviews of the 37mm Royal Oak Offshore highlight its exceptional wearability and thoughtful proportions, making it a more comfortable option for various wrist sizes compared to its larger 42mm counterparts. Enthusiasts frequently praise the flawless finishing of the steel case, which utilizes a mix of brushed and polished surfaces. While the bold design and diamond-set bezel are noted for their high visual impact, some users have found the folding clasp slightly finicky to operate. Overall, it is regarded as a robust and high-quality evolution of the original Royal Oak design that balances luxury aesthetics with sporty functionality.
