A watch has a switch mechanism 10 supported by a base 11 and a lid 13 that houses a generally conventional electric watch arrangement (not shown). The mechanism includes a semi-circular disc shaped finger tip engagable pusher 16 that can be rotated in either direction from a mean position, and also pushed radially inwards. Such movement of the pusher 16 produces radial movements of biassed plungers 23, 26 and 30 that are urged through respective apertures 24, 27 and 31 in a wall 12 of the base 11. As a result respective electrical circuits of the watch arrangement are closed to change watch functions. The mechanism 10 serves the same purpose as push buttons conventionally used in the prior art but is much easier for the user, especially if the watch is being worn on a wrist when watch functions need to be changed.
