How to choose the length of the clock of the quartz wall clock?
1. Remove the old pointer and measure the length of the needle, (from the center round hole of the minute hand to the top),
The size of the hour hand is determined according to the size ratio of the minute hand, and the size of the second hand is generally a little longer than the size of the minute hand;
2. Measure the radius of the dial, and then according to the radius of the dial, depending on the length of the clock, the length of the clock is generally 15mm shorter than the radius of the dial (but it depends on the design of the dial, because some The digital design of the dial is relatively large, so the length of the clock will be slightly shorter).
