The Geneva Stop Work design also known as Maltese cross was a major contributor to timekeeping accuracy in both Clocks and Watches. This stop-work mechanism when used with older style carbon steel springs helps to clip out the end portions of the mainspring where most torque variation occurs enabling the middle flat more constant torque portion of the mainspring to power the train. Very simple in its function as well as simplicity in design made the Geneva Stop work an inexpensive, commonly seen improvement on both watches and clocks.
