The name of the twelve zodiac signs is written on the edge. Outside the picture is a copper ring engraved with the names of 24 solar terms. Each solar term is divided into 15 squares, with one grid representing one day. Another copper circle outside the solar term circle is engraved with twelve hours
A clock has two long and two short stitches. Each cycle of a long needle is one hour, and each cycle of a short needle is 24 hours a day. The outer edge of the clock disk has teeth that engage and rotate with the gears of the timing system, indicating the movement and changes of the celestial constellation
This clock has two systems for running and reporting the time. The last chord can run seven days a week. The combination of astronomical constellations and solar term clocks is a characteristic of Suzhou clocks.
