"Pocket Watch With Independent And Lightning Seconds 1840"
RARE pocket watch with screwed back and screwed bezel, Breguet curved spiral anchor escapement, movement decorated with Geneva stripes on the back side and pearl decoration on the dial side. The movement has 2 barrels, it is signed JT Sontag Geneva. The case, back and bezel are in nickel and silver (see photo of the back). The small second hand is lightning and marks the quarter second. The operation is good, a revision will have to be considered later.
