Audemars Piguet Royal Oak Rose Gold — Blue Perpetual Calendar Dial | Ref. 26574OR.OO.1220OR.03

Gerald Genta handed watchmakers an architectural gift in 1972: an octagonal bezel fastened by eight exposed hexagonal screws, a form so coherent that it absorbs complications of any magnitude without losing its identity. Ref. 26574OR.OO.1220OR.03 is the living proof — a 41 mm Royal Oak in 18-carat rose gold whose blue perpetual calendar dial honours Genta's geometry while adding an entirely new dimension of mechanical depth through the Calibre 5134.

The Calibre 5134 is a self-winding perpetual calendar movement of exceptional thinness for its complication density, governing day, date, week, month, leap year, and astronomical moon phase displays without requiring correction until after the year 2100. The blue dial, richly textured with Grande Tapisserie patterning and set with applied pink gold index markers, presents the calendar information with visual clarity and chromatic harmony. The rose gold octagonal bezel with its eight sapphire-blue screws frames the display beautifully, and the screw-down crown ensures a secure seal.

Completed by an integrated 18-carat rose gold bracelet with AP folding clasp, this perpetual calendar Royal Oak achieves a degree of coherence — case, bracelet, dial, and complication in perfect accord — that few watches at any price point can match. Presented with box and papers and rated to an appropriate water resistance, Ref. 26574OR.OO.1220OR.03 is a collector's cornerstone: the Royal Oak at its most accomplished, dressed in the warmth of rose gold, and guided by one of the most sophisticated calendar mechanisms in contemporary manufacture production.
