Patek Philippe 5125 (Pre-owned - Excellent) — USD 86,995 on eBay

The Patek Philippe reference 5125 was introduced to commemorate the 125th anniversary of the company's registration in Geneva. It is a limited edition annual calendar model, distinguished by its unique case design featuring integrated crown guards, a departure from the more common Calatrava-style cases of many Patek Philippe annual calendars. This reference was part of a celebratory series that included variations in different precious metals. The watch features a 37 mm diameter case crafted from 18k white gold, housing the self-winding caliber 315 S IRM QA LU. This movement provides a power reserve of 45 hours and is visible through a sapphire crystal case back. The dial is presented in black, protected by a sapphire crystal, and the watch offers water resistance up to 30 meters. The bezel is smooth, complementing the overall case architecture. As a commemorative and limited edition piece, the 5125 holds particular interest for collectors seeking Patek Philippe's special releases. Its annual calendar complication, combined with the distinctive crown guard case, positions it as a notable example within the brand's contemporary offerings. The reference was produced for a limited period, adding to its collectibility.
