In 1925, the Swiss watchmaker Robert Cart patented a jump hour complication known as the Chronoscope. His approach featured an hour indicator, which moved around the dial, pointing at the correct minutes. His design became impressively popular during this period and was adopted by Breguet, Cartier and Patek Philippe, amongst others. The unconventional time display suited the Art Deco period perfectly, with its forward-thinking aesthetic and geometric lines. A few early Patek Philippe Jump Hour watches would be made in the 1920s, although the style was quickly discontinued.
This Patek Philippe Jump Hour 3969R was created as part of a selection of watches in honour of Patek Philippe's 150th anniversary, bringing back the historical design. A silvered dial sits comfortably within the rose gold, tonneau-shaped case, with the hour aperture placed prominently at 12 o'clock, and the minute track printed in black, adhering closely to the shape of the case.
The watch is powered by the calibre 215HG, a mechanical movement which was first introduced in 1975 and used in a Patek Philippe Ellipse. In fact, it is still used within some current pieces in the manufacture's catalogue. The caseback bears crisp engraving, with "Patek Philippe Genève - 150th Anniversaire - 1839 - 1989", in addition to the case number.
Notably, the watch is in exceptionally good condition - it was hardly worn by the original owner, and looks virtually as it was when it was brand new. Additionally, the watch is accompanied by a complete set of box and papers, giving the collector the opportunity to receive the watch as one might have back when it was first purchased.
