Patek Philippe Aquanaut 5164

Patek Philippe's Aquanaut 5164G-001 is a GMT watch with a 40.8 mm white gold case. The case measures 10.2 mm thick and pairs a screw-down crown with a sapphire display back. Inside is the self-winding calibre 26-330 S C FUS, which drives the Travel Time function alongside a central seconds display and a date indication linked to local time. The blue dial carries luminous hands and numerals for legibility. A rubber strap closes with a folding clasp in white gold. The 35-hour power reserve movement sits within a case that Patek Philippe rates to 30 metres of water resistance.
