How does an automatic watch work?
Unlike quartz watches, a traditional automatic mechanical watch does not need a battery to power its movement. Instead, it stores energy in a wound mainspring.
Inside the watch is a weighted rotor. As you move your wrist, the rotor turns and transfers energy through a winding mechanism to the mainspring. The spring gradually releases that energy through the gear train and escapement, keeping the hands moving.
Does it run forever?
No. If the watch is not worn or wound, its power reserve will eventually run out and it will stop. Depending on the movement, many automatic watches offer roughly one to three days of power reserve.
Automatic versus manual winding
Both use a mainspring. A manual-wind watch requires turning the crown to wind it, while an automatic watch can also wind itself through wrist movement. Some automatic movements also allow hand winding.
Why collectors appreciate them
Automatic watches are admired for their mechanical engineering, intricate moving parts, and repairable construction. They still need regular care and servicing.
