Abstract

To transmit the vibration of an alarm mechanism (1) to a users arm (8) with a high efficiency, the surface (4a, 5a) of a case back (4) in contact with the users arm (8) has a convex configuration on the side opposite to that on which the timepiece movement (2) is situated; thus ensuring contact between the case back (4) and the users arm (8).
