I have a very old faithful battery TAG that I wear most of the time. My newer TAG is wind up and , since I use it mostly on weekends, it is always dead when I reach for it. Correct time is quick to set but day/date was too much of a pain to fix. I hated that. After a few weeks with this winder, my watch has remained perfectly on time which makes it fully usable again.
