Abstract

In the mechanical selfwinding watch movement with an oscillating winding weight, the winding weight and the spring barrel driving the movement are pivoted coaxially, in the center of the movement, above the winding and the movement gears. The winding weight and the spring barrel have substantially the same thickness and they are on the same level. The spring barrel occupies almost the whole space in the path of the heavy sector of the winding weight. Due to the permissible size of such a spring barrel, the latter is able to store up an energy sufficient to keep the movement running during eight days at least.
