In Defense of Quartz Watches | Outside Online – Quartz watches are tougher than you think.. Watchmakers have invented all manner of methods for counteracting gravity, magnetism, fewer moving parts, quartz movements were not susceptible to shock; a battery meant it.

When Rolex Went Quartz: A Tale of the 1970s | WatchTime – USA. – Design studies were made with extremely stable high frequency (1.2 MHz and 2.4 MHz) quartz resonators with the ZT cut.

In the 1960s the electronic quartz watch was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechanical watch. Historically, this is called the quartz revolution.
The hands were driven mechanically through a wheel train. They were superseded by quartz watches, which had greater accuracy and durability due to their lower parts count. Recent automatic quartz watches, which combine mechanical technology with quartz timekeeping, are not included in this classification.
Long before there were quartz watches there were quartz clocks. The first was introduced in 1927. It wasn’t until the integrated circuit was invented that quartz movements could be made small enough to fit into a watch case. (The Seiko Astron didn’t actually incorporate an integrated circuit, but a type of hybrid circuit.
The first quartz wrist watch was Beta 1 and it had been built at the Centre Electronique Horloger. The first unit of a series of five was assembled and tested at the CEH in July 1967.
