In 2010, Miyota (Citizen Watch) of Japan introduced a newly developed movement that uses a 3-pronged quartz crystal that was exclusively produced for Bulova to be used in the Precisionist or Accutron II line, a new type of quartz watch with ultra-high frequency (262.144 kHz) which is claimed to be accurate to +/− 10 seconds a year and has a ...
Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency , so that quartz clocks and watches are at least an order of magnitude more accurate than mechanical clocks .
A "watch brand" is often—but incorrectly—used as a synonym of "watch manufacturer" or "watchmaker".Brands are distinct from manufacturers. There are brands of watches that are purely marketing constructs and are not associated with a specific company.
The first such watch was released in Germany in January 1988 and April of the same year in Japan (under the name Auto-Quartz).

Early automatic quartz movements were called AGS (Automatic Generating System).

Quartz movement of the Seiko Astron, 1969. The quartz crisis (Swiss) or quartz revolution (America, Japan and other countries) was the advancement in the watchmaking industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world.
The company was founded in 1983 through the merger of ASUAG and SSIH, moving to manufacturing quartz-crystal watches to resolve the quartz crisis threatening the traditional Swiss watchmaking industry. [2] [3] [4] The Swatch Group is the largest watch company in the world and employs about 31,000 people in 50 countries. [5]
The watch can be used to calculate no decompression times, and dive time. It was originally rated to a depth of 300 meters, later increased to 1,200 meters. [6] In 1968 DOXA became part of Synchron S.A. Soon after the introduction of the Sub300t, the Swiss watch industry was devastated by the introduction of quartz watches.
