DEVICE: MARINE NAVIGATION CLOCK CHRONOMETER

BRAND: YANTAI DAXIN PRECISION INSTRUMENT CO., LTD.

TYPE: CZ-05

The CZ-05 is a high-stability quartz marine chronometer designed for shipboard navigation systems. It provides an independent and reliable time reference for bridge operations, chart work, and astronomical navigation support.

It is built for continuous marine operation with long-term stability and resistance to environmental disturbances.
