CZ-05 Nautical Quartz Astronomical Clock/Chronometer
GENERAL DESCRIPTION
CZ-05 Nautical Quartz Astronomical Clock is a kind of high-precision timing instrument. Astronomical Clock is used 4.19 MHZ AT garden slice shape high-frequency quartz crystal oscillation frequency for time datum, using the capacitance frequency automatic temperature compensation, which can guarantee very high precision in a wide temperature range. Its time indication mode is second jump three needle longer analogue.
CZ-05 Nautical Quartz Astronomical Clock has the degree of stability of a second signal. In addition to school dial needle institutions abroad, it also has the device with speed and stop button. Astronomical clock is suitable for astronomy, earthquake, geodesy and laboratory.
