Abstract (en)
[origin: EP2685327A1] The button has a spring (10) arranged between a bottom face (58) of a head (9) and a retaining unit (54) partially derived from a cylindrical armature (50). Another spring (13) is wound around a push button stem (8). The latter spring has an end resting on the retaining unit and another end resting on another retaining unit (55). The latter spring is bent, and acts as a valve i.e. push button valve, if a pressure prevailing inside the timepiece is higher than a pressure prevailing outside the timepiece. A cylindrical spacer is made of a deformable material.
