As for the watch's overall operational status, let's be brief. 177-type movement with a combined pairs of the chain drive, chain drive up and down the installation of an unprecedented sapphire crystal glass lid, which can effectively reduce friction wear and tear, it can delight, to observe the movements power reserve up on the 8th. Tourbillon outer edge of the device a steel pinion,
cheap watches, and the middle of the bevel gear tooth addicted together, of the overall multi-level device to clockwise direction to promote. Jaeger-LeCoultre watch movements in order to reduce the thickness of a master, in particular, the structure will be downward-sloping Tourbillon 37 degrees, but also substantially increase the visibility of the movement. The other one helical gears with the same tilt angle, around the middle of the gear rotation, so that the inner structure of tourbillon continuous 360-degree rotation. Link to swing the structure of device and escapement device, from another one inside the aluminum outer ring gear, and the escapement wheel combination of small gear.
