Lot Essay

With Patek Philippe Certificate of Origin and Extract from the Archives confirming production of the present hunter case watch with enamel dial as well as Breguet numerals and its subsequent sale on 17 June 1930. Furthermore delivered with original fitted wooden presentation box containing a spare spring.

According to our research, the movement dates back to around 1891, while the dial and case were made around 1917. The watch movement was, therefore, assembled with this case and movement at a later date and sold in 1930.

To the best of our knowledge, the present watch has never been offered at auction before. The watch features attractive Breguet numerals and the numbers of the date in red on the dial. It is an added bonus that the watch is still accompanied by its original Certificate and box.

This complicated timekeeper impresses by its heavy case with a hinge consisting of five joints for both the front and back covers. Such hinges with multiple joints were reserved for more important watches as they added extra work to the case maker and are a sign of superior quality. Moreover, the watch houses a chronometric compensation balance and thereby underlines the high quality of the movement. Also referred to as the "Extra balance", this type of compensation balance is lighter and smaller than the Guillaume balance and was, therefore, used in thin or complicated watches.

It is interesting to note that the Patek Philippe watch with the movement number 80'527, which immediately precedes the movement number of the present watch, was sold at Christie's Geneva in November 2003 as Lot 99. The watch sold in 2003 came with a black dial and moon phases at nine o'clock and is now the property of the Patek Philippe Museum.
