Rare 8-days Art Deco Gold-filled Cornioley Pocket


Rare 8-days Art Deco Gold-filled
Cornioley Pocket Watch - circa 1930
This rare gold-filled 8-days (rare to find 8-days in a pocket watch) open-face pocket watch was made in Switzerland circa 1930.
Dial: The dial has black Arabic numerals with outer minute divisions and blued moon hands. The subsidiary seconds register at 9 o'clock (it is unusual to find subsidiary seconds at the 9, which makes this a valuable collector’s item). The dial is signed “Cornioley 8 days”.
Movement: The watch has a mechanical crown wind twin barrel 8-day movement and is held in an Art Deco case. It has a milled edge and foliate bezels, verso hinged at 6 o'clock. It is engraved with a symmetrical engine turned engraving in an art deco style. The movement of this watch, with its two-barrel gearing on the same pinion, is based on the principle first employed by Breguet on marine chronometers. With two barrels acting in opposite directions, the opposing direction of their force bears equally on the pivots, which suffer much less strain and friction, allowing the use of a much stronger mainspring to supply enough power for the 8-day movement.
This watch is in good working condition, but we cannot guarantee the long-term precision on 8-days and the regularity of an antique pocket watch.
Diameter = 48mm Weight = 58.80g
