CZ-03 Nautical Quartz Submarine Clock with 24-hour System
GENERAL DESCRIPTION
CZ-03 Nautical Quartz Submarine Clock with 24-hour System is a new product which is combined the latest electronic technology with the traditional mechanical clock manufacturing process. The clock movement is made of metal material. Submarine Clock is used high frequency, small temperature coefficient of quartz resonator for the frequency reference and it is used CMOS integrated circuit driving stepping motor that drives the pointer indicating time. All of the crystal and circuit are carefully screened and aging treated. Submarine Clock has 24-hour system and its dial indicator for 24 hours. Submarine clock is the chronometer instrument for submarine.
