Quartz Chronometer CZ-05

Quartz Chronometer is also called marine astronomical clock. It is the high efficiency quartz timekeeper, water-resistant and unaffected by humidity, shock, and magnetic force. The clock will still run when replacing the battery on a 40 hour back-up battery.

This product, a kind of high precision hour meter, adopts vibration frequency of 4.19 MHZ high efficiency quartz crystal in the form of AT tangential circle slice as the time reference, utilizes electric capacity temperature frequency for automatically compensation to ensure the pretty high travel time in relatively wide temperature scope, with the second skipping analogy type as the method of time indication. This product adopts two 1# batteries parallel connection for power supply, which can not only improve the reliability of working, but also facilitate the cell replacement and prevent the quartz from stopping when cell replacement. And the parallel connection of two batteries for power supply also prolongs the service life of the cell.
This product is with high stability second signal, and the device of acceleration, stop button, apart from collating with driving mechanism. This product, as time standard, is applicable to navigation,astronomy, earthquake, land measurement, lab, etc.
