ABSTRACT:
The watch has a winding weight comprising an arm 10a and an oscillating mass 10b. The arm is mounted for pivotal movement about the axis of a toothed ring 12 by way of which the spring barrel 20 is kept wound and which axis is offset with respect to the watch hand axis X, X'. The oscillating mass 10a is at the same level relative to the case back 6 as the spring barrel 20. The length L' of the winding weight is greater than the offset L and more than half the largest dimension of the case 6. The oscillating mass 10b thus occupies substantially half the casing of the watch and is almost as thick as the distance between the glass and the back 6 which is also the rear plate of the movement.
