Changing the date on an analog Timex watch is a straightforward procedure that makes use of the buttons or crowns on the side of the watch case. There are several different analog products, but the process for each is similar. Your Timex watch will typically come with a user guide that instructs you how to set the day on your watch. If you've lost the instructions or never received them, these guidelines may help.
