Audemars Piguet Royal Oak Offshore Steel — Blue Lady Tapisserie Diamond Bezel Chronograph 37mm | Ref. 26231ST.ZZ.D027CA.01

At 37 mm, the ref. 26231ST.ZZ.D027CA.01 occupies an elegant middle ground within the Royal Oak Offshore family — generous enough to carry the model's bold presence, refined enough to wear with the ease its female wearers demand. The stainless steel case, 12.4 mm thick, is paired with a diamond-set bezel carrying 32 brilliant-cut stones totalling approximately 1.02 carats, and a blue dial rendered in the Lady Tapisserie pattern — a finer-grained variant of the iconic guilloché that honours the Offshore's larger aesthetic while acknowledging its context.

The Calibre 2385 selfwinding chronograph movement powers this watch, delivering hours, minutes, small seconds and date alongside the chronograph complication, with approximately 40 hours of power reserve. Blue counters and a blue external zone extend the dial's chromatic harmony, while white gold applied Royal Oak hands with luminescent coating ensure legibility. The glareproofed sapphire crystal caseback reveals the movement, maintaining the transparency characteristic of the Offshore's sports watch positioning.

The watch is presented on a blue rubber strap with stainless steel AP folding buckle — an integrated choice that plays the watch's steel and diamond-set architecture against a casual, water-resistant foundation, with 50 metres of protection. For the collector seeking a ladies' Offshore chronograph that combines genuine horological substance with jewellery-grade presentation, this steel and diamond ref. 26231 represents precisely the kind of dual-register complication that defines the Offshore's enduring market appeal.
