Abstract (en)
[origin: JP2019164129A] To provide an annular rotation bezel system in which flexibility of a spring ring is increased in a plane and which can be produced easily.SOLUTION: An annular rotation bezel system 6 rotatable on a middle case 4 of a watch case 2 comprises: a rotation bezel 14; an annular holding ring 16; a ring with a tooth 18; and a spring ring 20 which can elastically deform along a radius. The spring ring 20 elastically cooperates with the ring 18 with a tooth, the ring 18 with a tooth and the spring ring 20 are held in an axial direction vertical to a plane of a movement by the annular holding ring 16, and any one of the ring 18 with a tooth and the spring ring 20 is coupled to the rotation bezel 14 in an angular state, the other thereof is coupled to the middle case 4 in an angular state, the spring ring 20 has at least one thin part 38 which increases flexibility, the thin part 38 has at least one tooth part 40 engaged to the ring 18 with a tooth elastically in a radial direction.SELECTED DRAWING: Figure 1
