How many parts are there in a mechanical movement?
The most obvious difference between a mechanical movement and a quartz movement is the power source. A quartz movement is powered by a battery, whereas the mechanical movement is driven by a mainspring that must be periodically wound either manually or by a self-winding mechanism. The force stored in the mainspring is then transmitted through a series of gears to power the balance wheel, a weighted wheel that oscillates at a constant speed. Making a mechanical movement is no
