Do clocks go faster or slower in winter?

The speed has little impact, but it will be faster in winter.

Reason:

What affects the speed of a clock is the swing amplitude of the balance wheel, which is controlled by a metal hairspring. The hairspring is a major factor. From the perspective of thermal expansion and contraction To analyze, cold will cause the hairspring to shorten and harden, so it will walk faster.

(Usually adjusting the speed of a watch is to adjust the length of the speed card on the hairspring. If the length decreases, the watch will be faster, and vice versa.
