Electronic movements, also called quartz actions, have few or no transferring elements, besides a quartz crystal which is made to vibrate by using the piezoelectric effect. A various electric powered voltage is applied to the crystal, which responds by converting its form so, in aggregate with a few digital additives, it features as an oscillator. It resonates at a specific notably strong frequency, that is used to correctly tempo a timekeeping mechanism. Most quartz moves are typically digital but are geared to drive mechanical hands at the face of the watch to provide a conventional analog display of the time, a feature most purchasers still choose.

In 1959 Seiko placed an order with Epson (a subsidiary enterprise of Seiko and the 'mind' in the back of the quartz revolution) to begin growing a quartz wristwatch. The mission changed into codenamed 59A. By the 1964 Tokyo Summer Olympics, Seiko had a running prototype of a transportable quartz watch which turned into used because the time measurements during the event.

The first prototypes of an digital quartz wristwatch (not just portable quartz watches as the Seiko timekeeping gadgets at the Tokyo Olympics in 1964) had been made through the CEH research laboratory in Neuchâtel, Switzerland. From 1965 via 1967 pioneering improvement work turned into completed on a miniaturized 8192 Hz quartz oscillator, a thermo-repayment module, and an in-house-made, committed included circuit (in contrast to the hybrid circuits used inside the later Seiko Astron wristwatch). As a end result, the BETA 1 prototype set new timekeeping overall performance facts at the International Chronometric Competition held at the Observatory of Neuchâtel in 1967. In 1970, 18 manufacturers exhibited manufacturing versions of the beta 21 wristwatch, inclusive of the Omega Electroquartz as well as Patek Philippe, Rolex Oysterquartz and Piaget.
