A multifunction analog electronic watch includes a battery, a circuitry block and a base plate made from a polymeric other electrically non-conductive material. A switching device for controlling application of the voltage from the power source to the circuitry block includes a switching member and two electrode patterns. The first electrode pattern is electrically coupled to the power source and the second electrode pattern is electrically coupled to the circuitry block. The switching member, which is normally biased away from the first electrode pattern and second electrode pattern is operable in response to external pressure for contacting the first electrode pattern and the second electrode pattern so as to provide an electrical path between the first electrode pattern and the second electrode pattern.

Switching arrangement for applying battery voltage to circuitry block in

A multifunction analog timepiece including a stem responsive to external regulation for controlling a displayed function. The stem is positionable at at least two steps. A clutch wheel is disposed on and movable along the stem. A setting element coupled to the stem is operable for direct contact with the clutch wheel. The setting element is in direct contact with the clutch wheel and only one of the steps of the stem.

Setting mechanism for an analog timepiece

A multifunction analog electronic watch includes at least two operating mechanisms to control the operation of a displayed multifunction in response to external regulation. The timepiece includes at least two clutch wheels, each clutch wheel disposed on and movable along an associated one of the operating mechanisms. A single setting element is coupled to each operating mechanism and to each clutch wheel for positioning the latter.
