Abstract (en)

[origin: US2022291636A1] A case element for a timepiece is described, having a through-hole and bearing a pushbutton including a tube, that is accommodated inside the through-hole and is closed by an actuating surface at its end oriented towards the outside, the actuating surface being intended to be pressed by a user in order to actuate a timepiece mechanism arranged inside the case element, wherein the pushbutton is made in one piece, of a bulk metallic glass, and further includes a connection surface which is arranged against the case element so as to establish a permanent, water-resistant connection with the latter, and wherein the actuating surface is able to move, with respect to the connection surface, in response to a pressure exerted thereon by the user. A corresponding production method is also described.
