The reference 5261R-001 brings a highly sophisticated complication to the casual elegance of the Aquanaut line. Its stunning blue-grey dial features a modern embossed Aquanaut motif, thoughtfully balanced by an inverted annual calendar layout displaying the moon phase at 12 o’clock alongside day, date, and month sub-registers. Crafted from 18K rose gold, the iconic rounded octagonal case showcases a masterfully executed interplay of polished and satin-brushed finishes. Powering this exceptional timepiece is the automatic Caliber 26-330 S QA LU, a self-winding mechanical movement visible through the sapphire crystal case back that automatically recognises months with 30 and 31 days, requiring only one manual correction per year.

The watch is supplied with its outer box, inner presentation case, leather folder, manual, correction stylus, protective cloth and warranty certificate dated 2026.

The watch will be sold with the remaining balance of a 5-year Patek Philippe warranty from original date of sale (Terms & Conditions apply).
