PATEK PHILIPPE | REFERENCE 701, A GILT BRASS SOLAR POWERED DOME TABLE CLOCK, MADE IN 1953 | 百達翡麗 | "型號701 鍍金銅製太陽能座鐘，機芯編號872586，外殼編號113，1953年製"

The Patek Philippe "Dome Clock" was introduced in the 1950s and invented a new method to powering a timepiece. Thanks to a photo-electric cell, the Dome Clock is powered by a movement wound automatically by illumination, with a daily light exposure for 4 hours at 200 lux sufficient to keep the clock running indefinitely. Often found at auctions with colourful enamel paintings, the present Dome Clock features the vanilla gilt brass case, decorated with an argyle pattern which serves versatile for all settings.
