Notes
The calibre of this watch with two barrel gearing on the same
pinion, is based on the principle first employed by Breguet on
marine chronometers and for quality watches fades sur le principe
des garde temps. The two barrels acting in opposite directions, the
opposing direction of thei
r force bears equally on the pivots
which suffer much less strain and friction and therefore allow to
use much stronger mainsprings in order to supply enough
power for an eight day going movement.
The company was listed in La Chaux-de-Fonds as late as 1960 as
"Eight Day Cornioley," as a continuation of F. Corniomey,
founded in La Chaux-de-Fonds, circa 1917.
