Patek Philippe Aquanaut 5164

Patek Philippe's Aquanaut 5164R-001 is a GMT watch cased in rose gold at 40.8 mm across. The case measures 10.2 mm thick and pairs polished and satin-brushed finishes with a screw-down crown. A self-winding calibre 26-330 S C FUS drives the watch, offering local and home time with day/night indication and a date coupled to local time, backed by 35 hours of power reserve. The sunburst brown dial carries luminous numerals and hands, and sits under a sapphire crystal, with a matching sapphire caseback showing the movement. The dark brown composite strap closes with a rose gold folding clasp. That screw-down crown keeps the case rated to 30 metres.
