In the early 1950s a joint venture between the Elgin Watch Company in the United States and Lip of France to produce an electromechanical watch – one powered by a small battery rather than an unwinding spring – laid the groundwork for the quartz watch. Although the Lip-Elgin enterprise produced only prototypes, in 1957 the first battery-driven watch was in production, the American-made Hamilton 500.
In 1954, Swiss engineer Max Hetzel developed an electronic wristwatch that used an electrically charged tuning fork powered by a 1.35 volt battery. The tuning fork resonated at precisely 360 Hz and it powered the hands of the watch through an electromechanical gear train. This watch was called the Accutron and was marketed by Bulova, starting in 1960. Although Bulova did not have the first battery-powered wristwatch, the Accutron was a powerful catalyst, as by that time the Swiss watch-manufacturing industry was a mature industry with a centuries-old global market and deeply entrenched patterns of manufacturing, marketing, and sales.

In the late 1950s and early 1960s, both Seiko and a consortium of Switzerland's top watch firms, including Patek Philippe, Piaget, and Omega, fiercely competed to develop the first quartz wristwatch. In 1962, the Centre Electronique Horloger (CEH), consisting of around 20 Swiss watch manufacturers, was established in Neuchâtel to develop a Swiss-made quartz wristwatch, while simultaneously in Japan, Seiko was also working on an electric watch and developing quartz technology.
One of the first successes was a portable quartz clock called the Seiko Crystal Chronometer QC-951. This portable clock was used as a backup timer for marathon events in the 1964 Summer Olympics in Tokyo. In 1966, prototypes of the world's first quartz pocket watch were unveiled by Seiko and Longines in the Neuchâtel Observatory's 1966 competition. In 1967, both the CEH and Seiko presented prototypes of quartz wristwatches to the Neuchâtel Observatory competition.
On 25 December 1969, Seiko unveiled the Astron, the world's first quartz watch, which marked the beginning of the quartz revolution. The first Swiss quartz analog watch – the Ebauches SA Beta 21 – arrived at the 1970 Basel Fair. The Beta 21 was released by numerous manufacturers including the Omega Electroquartz. On 6 May 1970, Hamilton introduced the Pulsar – the world's first electronic digital watch.
