Patek Philippe 5160 (New with box and papers) — USD 202,999 on eBay

The Patek Philippe Reference 5160 represents the brand's Retrograde Perpetual Calendar model in 18k white gold. Produced from 2006 to 2011, this reference combines perpetual calendar complications with retrograde displays in a precious metal case. The 5160 was offered exclusively in white gold during its production run. The watch features a 38mm case crafted from 18k white gold with a polished bezel and sapphire crystal. Water resistance is rated to 30 meters. The timepiece is powered by the automatic Caliber 324 S Q, providing 45 hours of power reserve. The watch is fitted with a leather strap. This reference appeals to collectors seeking a complicated Patek Philippe timepiece with both perpetual calendar and retrograde functions. The white gold case material and relatively compact 38mm diameter make it suitable for formal wear. The five-year production window from 2006 to 2011 establishes clear parameters for collectors tracking this specific reference within Patek Philippe's contemporary complicated watch offerings.
