Patek Philippe’s Aquanaut Travel Time 5164G is a seriously refined sports watch, pairing a 40.8mm white-gold case with a blue-grey embossed dial and matching composite strap. Powered by the self-winding Calibre 26-330 S C FUS, it features dual-time functionality, day/night indicators and a local-date display. A proper modern Patek that combines luxury, practicality and understated style.
