Patek Philippe 5060 (Pre-owned - Good) — USD 61,926 on eBay

The reference 5060 is a significant early iteration of the Aquanaut line, introduced in 1997. This model marked Patek Philippe's venture into a more contemporary, sport-oriented design, distinct from its established dress watch collections. It was presented as a robust yet refined timepiece, catering to a clientele seeking a versatile watch suitable for active lifestyles while retaining the brand's horological standards. The 5060 laid the groundwork for the Aquanaut's subsequent development and popularity. This reference features a stainless steel case with a distinctive octagonal bezel, measuring 35.6 mm in diameter. It houses an automatic movement, specifically the caliber 330 SC, known for its reliability and slim profile. The watch is fitted with a sapphire crystal, providing scratch resistance and clear visibility of the dial. The case design incorporates a screw-down crown, contributing to its water resistance. As an initial Aquanaut reference, the 5060 holds particular interest for collectors tracing the evolution of Patek Philippe's sport watch offerings. Its relatively compact size compared to later Aquanaut models appeals to those who prefer a more understated presence on the wrist. The 5060 was produced for a limited period, making it a notable piece for enthusiasts of the brand's modern history.
