HANDS Original


In the letter from Patek Philippe, dated July 28, 1980, it is stated that the present watch was open-faced and that the back was engraved with the initials ?EG?. The case was upgraded to hunting-cased and the monogram removed by Patek Philippe at the request of the former owner. 278 In 1776, in Geneva, Moise Pouzait invented the independent dead seconds mechanism in which the movement has two trains, one conventional, and the second with a sweep-seconds hand which can be stopped without stopping the main train. Adrien Philippe?s independent dead seconds mechanism differs radically from the conventional one based on Pouzait?s design. Philippe moved the entire "independent" train over the center bridge, allowing more room for the going train and the balance, which is larger, resulting in better timekeeping. There are fewer than two dozen recorded independent dead seconds watches by Patek Philippe, including the very first ones made by Patek and Czapek. This watch incorporates Adrien Philippe?s two patents concerning tandem winding: the first, for a "free", or "slipping", mainspring, patented on June 16, 1863 in France, and the second, for winding two mainsprings with one crown, Swiss patent No. 1017 of May 23, 1889. A similar watch was sold by Antiquorum, Geneva, April 24, 2004, lot 81. A virtually identical movement (No. 174021), is illustrated in "Patek Philippe, Genève", by Martin Huber and Alan Banbery, p.195.
