Highly accurate watch engine powered by an oscillating crystal that runs on a small battery. Autoquartz is a hybrid.
Movement that is powered by quartz crystal. The quartz is fitted with electrodes and vibrates when placed in an oscillating electric circuit. It then imparts constant frequency to the circuit.
Watch movement that is powered by a miniature battery, so there is no need to wind the watch. Watches with quartz movement can gain or loose as little as a few seconds per year.
A movement using an electrically powered quartz crystal.
Battery operated mechanism eliminating need to wind daily; analog watches only.
A battery operated watch with plus or minus 30 second per Year accuracy.
An electronic movement in a watch powered by a battery that causes vibrations in a tiny piece of quartz.
A movement that allows a watch to keep time without being wound.
A watch movement where time is "tuned" to, and measured by, the extremely rapid and consistent vibrations of a quartz crystal. Also known as "Electronic quartz movement".
Tells time with precision using an integrated circuit, a miniature battery and a quartz oscillator that vibrates at a high frequency.
A movement powered by a quartz crystal to vibrate.
A watch movement that works from the consistent vibrations of a quartz crystal. There is no need to wind a quartz watch.
A timepiece that uses an electronic oscillator and a quartz crystal to keep precise time. In 1928, W.A. Marrison of Bell Laboratories built the first quartz clock, accurate to within 1-2 thousandths of a second per day.
Quartz movement watches are watches that require battery, and the standard watches use quartz technology. The average life span of a battery is 2-3 years.
A watch with a mechanism powered by a "quartz crystal." The crystal vibrates when placed in an electronic field, thus powering the watch. Most affordable watches today have Quartz movements. Quartz watches are mostly battery operated.
A movement powered by a quartz crystal to. Quartz crystals are very accurate. They can be mass produced which makes them less expensive than most mechanical movements which require a higher degree craftsmanship.
