Abstract: The illustrated embodiment of my invention is a wrist watch having a watch case and a fixed seat outside of it. The watch case is movably mounted relative to the seat and is recessed within that seat. A spring normally holds the case in a rest position recessed within the seat. The case contains a quartz crystal, a circuit board, and an electro-optical data display at a window in the case. Manual actuation of a press-on member, specifically here a push button, against the resisting spring causes the case to move and thereby close a switch that causes the current time reading to appear on the display. Other displays occur successively if the case is soon enough manually moved part of the way back to its rest position and allowed to pop back up from there.
