Marine Chronometer Quartz CZ-05
CZ-05 type high frequency quartz Marine chronometer (including CCS certificate)
Highly accurate quartz crystal timekeeper. Water-resistant and unaffected by humidity, shock, and magnetic force. The clock will still operate when replacing the battery on a 40 hour back-up battery.
This product is a kind of high precision timing instrument, using the frequency of 4.19 MHz AT circular chip quartz crystal vibration frequency as the time reference, the use of capacitor temperature frequency automatic compensation, can ensure a wide range of temperature within a very high accuracy of travel.Its time indicator for the second jump three needle analog, this product uses two No. 1 battery parallel power supply, which can not only improve the reliability of the work, but also convenient to replace the battery, so that the quartz clock in the replacement of the battery will not stop, the other two batteries in parallel power supply also extends the battery life.
This product has a high stability of the second signal, in addition to the needle mechanism school, but also with speed, stop button and other devices, the product is suitable for navigation, astronomy, seismic, geodesy and laboratory as a time standard.
