Rapper Kanye West spotted wearing a Audemars Piguet

Kanye West marked his 39th birthday in characteristically understated fashion — at least by his standards — with an Audemars Piguet Royal Oak Perpetual Calendar Skeleton reference 25829OR locked to his wrist. The sighting is notable not simply because of the price tag, but because the 25829OR represents a level of mechanical ambition that places it firmly among the most serious complications in the Royal Oak family.

The reference 25829OR is built around a skeletonized perpetual calendar movement — calibre 2870 — that required Audemars Piguet's craftsmen to remove all non-essential metal from the bridges and plates while preserving the structural integrity needed to display day, date, month, moon phase, and leap year cycle simultaneously. The result is a dial that reads like an architectural drawing of time itself. The 18k yellow gold case measures 39mm, consistent with the classic Royal Oak proportions established by Gerald Genta's 1972 design, and the integrated bracelet remains one of the most ergonomically refined in fine watchmaking.

From a collector standpoint, skeletonized perpetual calendars from Audemars Piguet occupy a particularly coveted niche. The 25829OR was produced in limited numbers and has aged gracefully in the secondary market. Yellow gold Royal Oaks, long considered less fashionable than steel variants, have staged a significant reappraisal among serious collectors over the past decade, driven in part by a renewed appreciation for precious metal grand complications.

Kanye West has maintained a long, well-documented relationship with Audemars Piguet — the brand has appeared throughout his career as a recurring symbol in both his personal wardrobe and his lyrics. His choice of the 25829OR over more accessible Royal Oak references signals a collector's sensibility rather than simple brand recognition.

At a UK list price of approximately £98,000, the Audemars Piguet Royal Oak Perpetual Calendar Skeleton reference 25829OR commands a premium commensurate with its complications. On the grey market, clean examples in yellow gold have traded above retail, reflecting sustained demand for skeletonized AP perpetual calendars from this era. For a birthday watch, the 25829OR sets a high bar.
