Audemars Piguet Royal Oak 5402 "D-series"
The Audemars Piguet Royal Oak “Jumbo” Extra-Thin (reference 5402 D-series) is a legendary icon in the world of luxury watchmaking. Introduced in the early 1970s and designed by the legendary Gérald Genta, the 5402 was the original Royal Oak — a revolutionary fusion of haute horlogerie and avant-garde industrial design. This D-series, produced in the early 1980s, represents the final and most refined evolution of the original 5402, maintaining the integrity of the original design while benefiting from incremental refinements in finishing and construction.
The slim stainless steel case, measuring 39mm in diameter and just 7mm in thickness, established the blueprint for modern luxury sports watches. Its angular, octagonal bezel with exposed white gold screws, along with the integrated bracelet, creates a seamless and distinctive silhouette that remains unrivaled to this day. The D-series features a beautifully aged dark blue "Petite Tapisserie" dial, now taking on subtle tropical hues with time — a hallmark of authenticity and vintage charm. The applied white gold hour markers and baton hands ensure excellent readability while maintaining the watch’s minimalist aesthetic.
Inside the case beats the ultra-thin Calibre 2121, an in-house automatic movement developed in collaboration with Jaeger-LeCoultre. At just 3.05mm thick, it remains one of the slimmest full-rotor automatic movements ever made. Renowned for its smooth operation and high level of finishing, the Calibre 2121 features a suspended rotor and no seconds hand — a signature of the 5402 line — giving the watch a serene, timeless character. The movement offers a power reserve of approximately 40 hours.
Collectors value the D-series for its rarity, vintage appeal, and status as the final chapter of the original Royal Oak 5402 reference. The case and bracelet show gentle wear consistent with age but remain in exceptional condition (graded 8.5/10), with sharp lines and a clean dial. This piece is accompanied by its original box and papers — a true rarity — adding to its authenticity and long-term value as a collectible.
