A [watch winder for rolex](https://www.roroos.com/rolex-watch-winder-box-for-10-automatic-watches-black.html) is a device that helps to keep your Rolex watch wound when it is not being worn. When a Rolex watch is not in use for an extended period of time, it will stop running and require manual winding to get it started again. This can be a hassle for those who want to wear their Rolex watch on a daily basis and don't want to spend time manually winding it every time they put it on.
