Czapek has announced the acquisition of watch No. 535 at Sotheby's Important Watch auction. The timepiece, made by Patek, Czapek & Cie’s in 1842, is a very rare and early yellow gold open faced stem winding cylinder watch. Purchase was made possible by the joint efforts of twenty Czapek & Cie shareholders. It represents a historic moment for the company on its way to re-establishing Francois Czapek’s name and fame and contribute creatively to the world of independent high-end watchmaking.
The lot was bought for 65,000 Swiss Francs. Patek, Czapek & Cie’s Reference No. 535 is a rare horological treasure. In 1839, Francois (formerly Frantisek) Czapek and Anton de Patek launched a six-year-long joint watchmaking business. Watch No. 535 is one of only forty-two pieces that was made with the stem winding system, otherwise known as keyless watches. This makes it one of the earliest surviving pieces.
Patek, Czapek & Cie used stem winding systems made by Louis Audemars of Le Brassus from 1839 to 1845. Audemars was considered one of the pioneers of the keyless watch and sold unfinished movements to many firms in Geneva including Patek, Czapek & Cie. Though Jean Adrien Philippe is known as the inventor of the modern keyless stem-winding mechanism for watches, his stem-winding system only got patented in 1845 (French patent No. 1317).
The reference No 535 has a diameter of 47.5 millimetres. It is also atypical for its large size, which was likely due to the space needs of the stem winding system. It features a pendent winding mechanism, an exquisite engraved dial, and an engraved damask-style yellow-gold case with a lion in the center. The watch comes with archival documents confirming the year of manufacture as 1842 and date of sale on April 29, 1844.
