Audemars Piguet Royal Oak 50th Anniversary Rose Gold Diamond Bezel — Khaki Green Dial | Ref. 15551OR.ZZ.1356OR.03

Few commemorative releases in recent horological history have generated the sustained desire of the Royal Oak's 50th Anniversary editions of 2022. The Ref. 15551OR pays tribute to five decades of Genta's stroke of genius by pairing 18-carat pink gold with a khaki green dial — a combination that feels simultaneously celebratory and effortlessly contemporary. The octagonal bezel is set with brilliant-cut diamonds, whose cold brilliance plays against the warm blush of the gold case in a pairing of calculated contrast.

The Grande Tapisserie guilloche dial in khaki green is among the most coveted colour executions in the modern Royal Oak canon. Under natural light the surface transitions from warm olive at the outer edge to a richer, almost military green at the centre, with the raised relief of the tapisserie adding dimensionality that changes with every shift of the wrist. Applied gold hour-markers and matching Royal Oak hands complete the dial, with a date window positioned at three o'clock. The movement — Calibre 5800 — is a self-winding manufacture calibre offering approximately 50 hours of power reserve, visible through the transparent sapphire caseback.

The 37 mm pink gold case sits on an integrated rose gold bracelet, its central links polished to a mirror finish and flanks brushed to recall the signature alternating surface treatment of the original 1972 design. The AP folding clasp provides refined, rattle-free closure. At 50 metres water resistant, this is a 50th Anniversary piece with full sporting credentials — a watch equal to the legacy it celebrates.
