Do you own an automatic watch? Did you know that automatic watches want to be worn every day? The mechanisms that help them keep time require movement to stay engaged. In other words, they are designed to stay on your wrist, and they will keep time by drawing energy from each of your movements. But what happens when you can’t wear your watch for a few days? That’s where an automatic watch winder comes in.

Why do you need an automatic watch winder?

Have you ever wondered how your automatic watch keeps time? As long as you are wearing it, it never seems to stop or lose time—but have you noticed that it’ll slow down or even stop if you leave it on your dresser for any length of time? It hasn’t just given up on life because you’ve moved onto a different, probably younger watch model; there’s a reason (beyond your blatant neglect) that has caused your watch to die: it’s a self-winding watch, and that means you are its pendulum.

Automatic watch or grandfather clock, all self-winding clocks operate based on the same principle: movement triggers a weight that moves the clock gears. With an automatic or self-winding clock, the movement puts tension on a spring, and that spring winds the clock, or moves the clock gears, allowing it to keep regular time. The cool thing about an automatic watch is that it doesn’t need the regular swing of a pendulum to allow it to keep time. The spring is outfitted with collects and holds tension, allowing it to be distributed evenly, or rather timely. That means any of your movements will add tension to that mainspring, and no matter how random your movements are, your watch will keep perfect time. However, when your watch doesn’t move, the spring loses tension, and your watch will slow down and then stop. That’s where an automatic watch winder comes in handy.

What is an automatic watch winder?

Essentially, an automatic watch winder is a watch box, but unlike most watch boxes, which remain still and are designed with the purpose of protecting your watch alone, an automatic watch winder will protect your watch while also moving it in mimic of human motion. This will keep the self-winding mechanism of the watch working. That way, when you come back to your watch, after a day, a week, a month, or even longer, it will still be keeping perfect time.

How does it work?

An automatic watch winder looks exactly like a watch box. It is a case with a set place to secure your automatic watch. You can even get automatic watch winders that can house multiple watches, in the event that you have more than one that needs to be maintained. The watch winder moves the watches in a gentle, circular pattern, mimicking the motion of a wrist, thereby keeping your watch (or watches) running on time.

A further benefit is that, over time, your watch’s lubricants could congeal if it does not move enough. This will diminish accuracy, and it could even prevent your watch from working at all if it is left long enough. Placing your watch in an automatic watch winder will allow the circular patterns of motion to prevent the lubricants from sitting still and then congealing, and that will keep your watch working accurately.
