Accompanied by Patek Philippe Certificate of Origin and Extrait des Registres, five original timing sheets from the Geneva Observatory and Patek Philippe wooden presentation box.
The present watch is amongst the most impressive tourbillon watches by Patek Philippe ever offered at auction. It was conceived by the celebrated watchmaker, inventor and engineer James Pellaton from LeLocle during the years 1943 and 1944, then delivered to Patek Philippe in Geneva. Its movement was finished by Hermann Heck and the tourbillon cage by André Bornand, both renowned watchmakers in their workshops. During the years 1945 until 1957, the present watch has been participating in numerous Category A timing contests at the Geneva Observatory. In 1948, it achieved with a third price the highest classification of all Patek Philippe watches presented during this competition. The most gifted and prominent precision adjusters, François Moudoux, André Zibach and Jan Wenke prepared and adjusted the movement for these contests.
It is important to mention that the present watch combines all aspects of the highest quality, making it a superb example for the demanding collector. One of the most discerning complications, the tourbillon regulator, fitted in a state of the art gold case with hidden hinges, fully documented with certificates and timing extracts, in as good as unused condition and directly from the first owners collection.
It is furthermore interesting to mention that the watch was overhauled by Patek Philippe in 1999.
