Patek Philippe - Early Keyless Winding Patek Philippe & Co, à Genève, No. 12120. Made circa 1860. Fine and very rare, 18K gold pocket watch with Adrien Philippe’s first patented stem-wind and handsetting mechanism of 1845 without coasting. Four-body, “bassine et filet”, engine-turned and polished with vacant catouche, flat-topped winding crown, reeded band. Hinged gold cuvette. White enamel with radial Roman numerals, outer minute track, subsidiary seconds. Blued steel spade hands. 16’’’, frosted gilt, bar caliber, 8 jewels, wolf’s tooth winding, cylinder escapement, plain three-arm balance, blued steel flat balance spring, index regulator. Cuvette signed and numbered, case numbered and stamped L.O. Diam. 40.5 mm. Notes The present watch uses Adrien Philippe’s first winding and hand-setting mechanism, French patent No. 1317 of April 22, 1845. The winding pinion is fixed to the winding shaft. For winding the crown it must be turned clockwise and cannot be turned back with that typical ratchet noise. To disengage the winding in order to set the hands, the winding crown can be pulled out. Very few watches survive with this early winding mechanism without coasting.
