Will my watch still be running?

Pick your movement, or enter its power reserve, and when it was last full. We'll tell you whether it makes it to your deadline.

Movement Choose a movement… Power reserve (hours)

Last fully wound, or taken off Needs to be running at

For an automatic, use the time you took it off after a full day's wear. Worn only briefly, it may have less than its full reserve.

Stop checking. Get reminded.

Watch Winder does this for every watch you own, all the time, and nudges you a few hours before any of them stops.
