Trying to reset time on timex 1440 sports watch

Here's a link to some Timex watch manuals. I looked at the one for the 1440 but I couldn't tell if it was for your watch or not.

The following site has Timex manuals also.

If you can't find your watch on these sites, perhaps some of the similar watches will give you a clue as to how to set the time.

Good luck!
