mcdevito75 here, Sorry to hear of your disappointment with your Timex watch, thru the years quality of workmanship and parts may have fallen a bit, try a new battery in your timex, a high quality Battery. Anyway here is Timex Customer service number, 800-448-4639 Regards, Mike D

mcdevito75 here, Your watch (Timex) may have a 2 position stem. Push the stem (winder) all the way in, NOW just lift the stem a little to it:s first position, this should allow the date, (number ) to change, change that number to the date before the date you want, NOW pull the stem out to set the hands, rotate the hands to set proper date and time.

You have to adjust the date every February (28 or 29 days), April, June, September and November (each 30 days). Self adjusting calendars are called Perpetual Calendars and this feature is quite expensive, especially in mechanical watches. Your watch has calendar ring with 31 days printed on and the simple calendar mechanism which is changing dates from 1 to 31 inclusive,day after day, so, when the 30-day month is ending and there is no 31st date to follow, your calendar is showing 31st anyway,instead of 1st of the next month. This is when you have to adjust date. Now about the date adjusting. If you pull out crown gently, you will notice there are two clicks (positions), not just one. So the first click, when crown is not pulled out fully, is exactly for day/date adjustment. If you pull the crown further out, watch is in hand adjustment mode. Try it carefully and you will find out the right position.
