Audemars Piguet Royal Oak Steel — Silver Grande Tapisserie Dial | Ref. 15500ST.OO.1220ST.04

Gerald Genta's 1972 masterwork reaches its contemporary apex in the Royal Oak reference 15500ST — a 41 mm stainless steel statement that consolidates half a century of design authority into a single, sculpted form. The eight-sided bezel, secured by its signature hexagonal screws, remains as architecturally arresting as ever, its brushed and polished alternating surfaces catching light with a precision that speaks to the watchmaker's craft as much as the metalworker's art.

At the heart of this timepiece beats Calibre 4302, Audemars Piguet's in-house integrated automatic movement delivering approximately 70 hours of power reserve from its twin barrels. The movement operates at 28,800 vph, offering a sweeping seconds hand of notable fluidity. Visible through the sapphire exhibition caseback, the elaborately decorated rotor and bridges are finished to the exacting standards expected of Le Brassus — côtes de Genève striping, bevelled edges, and blued screws throughout.

The silver-toned dial presents the iconic Grande Tapisserie guilloché pattern — a hobnail motif applied with meticulous regularity across the entire surface — punctuated by white gold applied hour-markers and matching Royal Oak hands with luminescent coating. At 10.4 mm thin, this 41 mm steel bracelet model occupies the sweet spot between the original Jumbo and the sportier Offshore, making it the quintessential daily companion for the discerning collector who demands horological rigour without sacrificing wearability. Water resistance to 50 metres completes the brief.
