Rougois Mechanique Skeleton watch (pronounced “Roojwa”). Beautifully decorated mechanical wind up or automatic movement with 17-22 jewels. This is not only a very functional watch but also captivating and mesmerizing to look at the skeletal movement in motion. Your watch has 17-22 jewels which serve two purposes in a watch. First, they reduce friction of movement which can increase accuracy. Friction in the wheel train bearings and escapement causes slight variations in the impulses applied to the balance wheel, causing variations in the rate of timekeeping. The low, predictable friction of jewel surfaces reduces these variations. Second, they can increase the life of the bearings. In un-jeweled bearings, the pivots of the watch’s wheels rotate in holes in the plates supporting movement. The sideways force applied by the driving gear causes more pressure and friction on one side of the hole. In some of the wheels, the rotating shaft can eventually wear away the hole until it is oval shaped, and the watch stops.
