As a follow up to my earlier thread related to my watch losing 5 minutes in one day, I reset the watch sunday and it is still running totally accurate. I am beginning to believe that the issue was the lack of activity with my day (office job) and the power reserve getting so low (after 3 weeks) that the watch had stopped for a short period of time before starting again. That makes more sense than me setting the watch incorrectly or a mechanical issue with the watch which I dont believe exists. I am thinking about a watch winder and have no knowledge about them. When you have a watch winder, do you put the watch into it every night or is it something that is done less periodically? Also, what would people recommend for an inexpensive winder that has worked well for them? I guess my concern would be something that holds the watch securely and a winder that will not adversely effect the watch in any way mechanically by using it every night or at whatever interval is appropriate. Thanks for your assistance and I am happy that there seems to be nothing mechanically wrong with my Seamaster 300.
