Abstract

The electronic watch includes a position-responsive switch, for automatically energising the digital display (9) for a given period, when the wearer's arm is brought into a specific position. The position-responsive switch employs a metal ball (4), e.g. a drop of mercury, enclosed in casing allowing the ball (4) to attain one or more stable positions (A, B, C) in dependence on the orientation of the watch relative to the vertical (x1, x). In each stable position (A, B, C) the metal ball (4) bridges a pair of switch contacts, one pair of which allow the digital display (9) to be energised. The ball (4) may have two further stable positions, both allowing recharging of the capacitor in the timing circuit, determining the period for which the display (9) is energised.
