For its 150th anniversary, Patek Philippe included among its commemorative timepieces a tonneau-shaped wristwatch with a jumping hour in an aperture and centre minutes. This piece, the Reference 3969, has become a coveted collector's item, especially since this type of complication, originally produced in the 1920s, is no longer available in the manufacturer's regular collection. For its 175th celebration, Patek Philippe has continued its tradition of exclusive models by developing the Jump Hour Reference 5275, whose movement and appearance unite haute horlogerie and rare handcrafts.
The exceptional calibre 32-650 HGS PS is made of 438 parts and features an exclusive striking mechanism that makes the Reference 5275 a delight for the ear as well as the eye. At the top of each hour, a hammer strikes a single blow on a gong, in perfect synchrony with the instantaneous jump in the hour aperture. This completely new function recalls Patek Philippe's unparalleled mastery in the field of striking watches. The sound indication may be deactivated at will, using the small slide at 10 o'clock. A patented lifting lever secures the system against accidental mishandling.
Preserved in fantastic condition, this highly sought after reference could very well be the top piece in any serious collection, for its extremely small production quantity and its historical significance.
