Patek Philippe 5164G (Pre-owned - Excellent) — USD 158,995 on eBay

The Aquanaut Travel Time reference 5164G is a white gold iteration of Patek Philippe's dual time zone model within the Aquanaut collection. This reference maintains the distinctive rounded octagonal case shape and integrated strap design characteristic of the Aquanaut line, while incorporating a highly functional complication for travelers. It offers a clear and intuitive display of a second time zone, making it a practical choice for collectors seeking a sophisticated yet robust travel watch. This timepiece features a 40.8 mm white gold case, housing the self-winding caliber 26-330 S C FUS movement. The movement provides a power reserve of approximately 35-45 hours. A sapphire crystal protects the dial, ensuring durability and legibility. The case design, with its screw-down crown, contributes to the watch's water resistance, suitable for daily wear and light aquatic activities. The 5164G appeals to collectors who appreciate the blend of Patek Philippe's technical prowess with the more contemporary and sporty aesthetic of the Aquanaut. Its white gold construction elevates the model, offering a discreet luxury alternative to its steel counterparts. The Travel Time complication, with its local and home time indicators and day/night apertures, is a key draw, providing both utility and a refined mechanical display.
