In certain escapements (such as the duplex escapement), the hand improvements every two beats (full period) with the balance wheel, usually 1/2 second in Those people watches, or simply each 4 beats (two durations, one second), during the double duplex escapement. A really gliding second hand is achieved with the tri-synchro regulator of Spring Push watches. The entire hands are Usually mechanical, bodily rotating over the dial, While a number of watches have been produced with "fingers" that are simulated by a liquid-crystal Screen.

This can make it inconvenient to employ In case the watch is remaining worn on the right wrist. Some makers supply "remaining-hand generate", aka "destro", configured watches which shift the crown on the remaining aspect[57] creating sporting the view simpler for remaining-handed individuals.
