Patek Philippe 5976 (Pre-owned - Good) — USD 417,246 on eBay

The Patek Philippe Nautilus Ref. 5976/1G-001 was released in 2016 to commemorate the 40th anniversary of the Nautilus collection. This reference stands out within the Nautilus line for its enlarged case dimensions, offering a more contemporary presence while retaining the collection's distinctive porthole-inspired design. Crafted in 18K white gold, the watch features a monobloc case with a diameter of 44mm (10-4 o'clock) and a thickness of approximately 12.9mm. It is powered by the self-winding mechanical caliber 324 S C, visible through a sapphire-crystal case back, offering a power reserve of 35-45 hours. The dial is blue with a horizontal embossed pattern, featuring baguette and brilliant-cut diamond hour markers. As an anniversary edition, the Ref. 5976/1G-001 holds particular significance for collectors, representing a specific moment in the Nautilus's history. Its limited production and unique design elements, including the anniversary inscription on the dial, contribute to its desirability and position within the secondary market.
