What is the winding mechanism on a watch called?

In a mechanical watch the watch’s gears are turned by a spiral spring called a mainspring. In a manual watch energy is stored in the mainspring by turning a knob, the crown on the side of the watch. Then the energy from the mainspring powers the watch movement until it runs down, requiring the spring to be wound again.

How does a wind up watch work?

On self-winding (automatic) watches, a rotor is attached to the watches movement so that when you move your wrist, the rotor spins and winds the watch back up again by tightening the mainspring. A hand-wound watch has no rotor and therefore needs to be wound by hand in order for it to work.

What happens if you Overwind a mechanical watch?

Whenever the mainspring is wound completely, the rotor will stop turning in the course where the mainspring is wound. Thus, overwinding an automatic watch is not possible. This mechanism will, in fact, undo the winding motion happening on the mainspring, thereby keeping the watch’s functionality intact.

Is mechanical watch automatic?

In mechanical movement watches, the user should manually wind up the spring while in an automatic timepiece, the watch winds the rotor automatically using the energy it accumulated from the user’s wrist movements. This process makes the watch works even if you take it off at night.

How do mechanical watch movements work?

Automatic movement, a direct descendent of mechanical movement, employs a weighted rotor mechanism to allow a watch to wind itself. As the wearer rotates his wrist while wearing the watch, the movements engage the weighted rotor, spinning to self-wind the mainspring inside the watch.

How do automatic mechanical watches work?

An automatic watch movement uses a rotor, or metal weight, to power the timepiece. The rotor will oscillate freely within the watch. Every time the wearer moves their wrist, the rotor spins. That intrinsic spinning motion is transferred into energy that winds the mainspring in the watch automatically.

How much do you wind a mechanical watch?

As a rule, it takes approximately 20 to 30 turns of winding to keep your mechanical watch running smoothly. Most manual wound watches offer resistance at the crown when they are properly wound.

When should you stop winding a watch?

Stop winding when you first feel resistance. Try to wind your watch once a day. A watch typically keeps best time when the mainspring is above half tension. The typical watch has about a two-day power reserve so winding it up before you strap it on each morning is a good habit to form.

How do you know if a mechanical watch is fully wound?

Most watches will reach maximum power by winding the crown 30 to 40 times but this can vary. The minute you feel resistance, the watch is fully wound. If your watch is new and you’re feeling unsure, aim to wind the crown 30 times to start with and work your way up from there.

Should you fully wind a mechanical watch?

Is it dangerous to fully wind a mechanical watch? No, it’s not dangerous. Most mechanical watches (automatic or manual winding) feature at least a 38 hours power reserve. Many more watches now feature a 70 to 80 hours of power reserve.
