The intricate world of watch gears, often referred to as a watch movement, is a marvel of mechanical engineering. The core mechanisms such as the crown assembly, mainspring, and dial train work in harmony to keep time. The crown, the only point of contact between the wearer and the watch movement, is connected to the winding stem and can be pulled out to access different settings. The mainspring, a thin strip of hardened metal coiled to form a spring structure, releases its power via the mainspring barrel. The dial train, a series of interlocking gears, drives the timekeeping hands and other wheels within the movement.
