Patek Philippe
Patek Philippe is widely regarded as the finest watch manufacturer in the world, a Geneva maison founded in 1839 by Antoine Norbert de Patek and François Czapek, before Patek partnered with Adrien Philippe — inventor of the keyless winding system — in 1845. The brand has never been sold to a conglomerate, remaining under independent family ownership since 1932 under the Stern family, a fact that collectors cite as a guarantee of the watchmaking philosophy's continuity. Patek Philippe's roster of achievements is extraordinary: the most complex pocket watch ever made (the Graves Supercomplication, 1932), the invention of the perpetual calendar wristwatch and the gyromax balance wheel, and consistent production of the most expensive wristwatches ever sold at auction. The pre-owned Patek Philippe market is among the most liquid and price-stable segments of the luxury watch secondary market, driven by the brand's genuine scarcity, consistent demand, and the famous advertising line that each owner is merely custodian of a watch for the next generation. Pre-owned Patek Philippe references span the Calatrava, Nautilus, Aquanaut, Complications, and Grand Complications families. DeMesy & Co. in Dallas has been authenticating and sourcing pre-owned Patek Philippe watches since 1987, with the expertise this category demands.
