Audemars Piguet Royal Oak Selfwinding Bi-Metal 37mm — Silver Grande Tapisserie, Pink Gold Accents | Ref. 15450SR.OO.1256SR.01

The 15450SR occupies a precisely calibrated position in the Royal Oak family: 37 mm in diameter, 9.80 mm thick, and constructed in a harmonious marriage of stainless steel and 18-carat pink gold that AP designates with the 'SR' suffix. The case integrates a pink-gold bezel and screw-locked crown against brushed and polished steel flanks, producing a bi-metal composition that flatters a broad range of wrists and wardrobes. A glareproofed sapphire caseback invites inspection of the movement beneath, reaffirming that what lies inside is every bit as considered as what lies without.

Driving the 15450SR is Calibre 3120 — AP's robust and thoroughly proven in-house automatic movement — offering approximately 60 hours of power reserve across twin barrels, oscillating at 21,600 vph. The 3120 provides hours, minutes, centre seconds, and a date aperture at 3 o'clock, its self-winding rotor crafted in 22-carat gold and engraved with the Royal Oak motif. Decorated with circular graining, bevelled bridges, and Geneva stripes, the movement is a refined engine for an equally refined exterior.

The silver-toned Grande Tapisserie dial — its larger hobnail pattern distinguishing it from the Jumbo's Petite Tapisserie — is enriched by applied pink-gold hour-markers and Royal Oak hands with luminescent coating, ensuring confident readability in any lighting condition. The integrated bracelet combines brushed steel links with pink-gold centre links, fastened by an AP folding clasp — a detail that underlines the considered craftsmanship running from crown to clasp. At $36,995, the 15450SR is an accessible gateway into the upper register of the Royal Oak family, offering genuine bi-metal sophistication at a proportioned scale.
