Patek Philippe 5180 (New with box and papers) — USD 103,000 on eBay

The Patek Philippe Complications Reference 5180 is a highly exclusive and technically sophisticated timepiece, distinguished by its skeletonized movement and the rarity of its case material. This reference showcases Patek Philippe's mastery in haute horlogerie, particularly in the art of openworking, allowing for an unobstructed view of the intricate mechanical components. It represents a significant offering within the Complications collection, appealing to collectors who value both mechanical artistry and material exclusivity. The 5180 features a meticulously hand-engraved, skeletonized self-winding mechanical movement, Caliber 240 SQU. The case is crafted from titanium, a material rarely used by Patek Philippe, contributing to its exceptional rarity. The case diameter is 39mm, providing a balanced presence on the wrist. The movement offers a power reserve of 48 hours and is protected by a sapphire crystal, allowing for clear visibility of the intricate dial-side mechanics. This reference holds particular appeal for collectors due to its extreme scarcity, especially in titanium. The limited number of titanium Patek Philippe wristwatches ever produced positions the 5180 as a highly sought-after piece for those focusing on unique and rare material executions. Its combination of a complex skeletonized movement and an uncommon case material makes it a notable entry in the brand's modern production.
