With the Omega Marine Chronometer wristwatch movement of 1974 as a basis a Quartz Marine Chronometer clock movement was designed with a high-frequency 4.19 MHz (2 22 or 4,194,304 Hz) quartz oscillator that should be capable of an accuracy of approximately ± 0.01 second/day. Where quartz elements were usually lens-shaped, this one was barrel ...
The first such watch was released in Germany in January 1988 and April of the same year in Japan (under the name Auto-Quartz). [3] The watches had an average monthly rate of ±15 sec and provided 75 hours of continuous operation when fully powered. Early automatic quartz movements were called AGS (Automatic Generating System).
These production watches were accurate to 5 seconds per month, far better than any automatic or manual wind chronometer at the time and an enormous leap in accurate time keeping. The movement was a modular design and components were manufactured by individual companies (such as Omega who made the micro motor) and then assembled at three workshops.
Each movement is individually tested for several consecutive days, in five positions and at three temperatures. Any watch with denominations "certified chronometer" or "officially-certified chronometer" contains a certified movement and matches the criteria in ISO 3159 Timekeeping instruments—wristwatch chronometers with spring balance ...
Basic quartz wristwatch movement. Bottom right: quartz crystal oscillator, left: button cell watch battery, top right: oscillator counter, digital frequency divider and driver for the stepping motor (under black epoxy), top left: the coil of the stepper motor that powers the watch hands.
The movement had one large circuit on the rear of the watch which controlled both the analogue movement (based on calibre 1320) [3] and digital LCD elements. The Chrono Quartz was originally run on two mercury 323 batteries having a running time of 26 months, this was replaced by the silver oxide 393 battery having a running time 15 months.

The G-Shock then was conceived as a watch which would have "triple 10" resistance, meaning it would have a battery life of 10 years, have a water resistance of 10 bar and could survive a fall of 10 meters. [2] A team of three individuals was selected by Ibe which was known as "team tough".
