A meca-quartz movement is a hybrid, with two distinct mechanisms working in partnership: in a meca-quartz chronograph, the timekeeping functions are controlled by a quartz movement, while the stopwatch functions of the chronograph are recorded by a mechanical module. Both functions are powered by the same battery. Meca-quartz builds on the strengths of these two types of movements: the accuracy of quartz with the crisp feel and performance of a mechanical chronograph. Compared to a conventional fully-mechanical chronograph, a watch with a meca-quartz movement can be slimmer, more durable, and more reliable, cheaper to maintain and faster to service.
