How to advance date 4 or 5 days on a Timex T40021
This watch should have a "quick set" date function that lets you advance the dates by turning the setting crown. To get the watch in this mode, pull the set stem out half-way. At that point, turning the setting crown will advance the date on the watch without turning the hands. One some watches, finding the right position for the set stem can be a bit tricky--either it's not out far enough or it's out just a bit too far and the time hands turn. You may have to try pulling the stem in and out a few times to get it just right.
A word of advice: watches are generally designed to advance the date, not to turn it back. It's suggested that if you need turn the date back, you actually advance the date wheel up to 30 days to get to the date you want. Some watches do permit you to turn dates backwards, but I prefer not to risk the chance of hanging up the little springs and mechanism that are designed to advance the date indicator.
One final note: I have serviced several Timex mid-size (ladies or kids size) Expedition watches that lack a quick-set date. Many Timex watches in that size do have a quickset date like I've just described to you, so I have no idea whether these watches happen to have a cheaper movement or if they have some internal damage (it's been the same model each time). At any rate, for those watches, I have had to use the incredibly slow and painful process of advancing the time 24 hours to advance the date. With those watches, if the date is too far advanced by a day or two, it may be easier to stop the watch for 24-48 hours until the date is correct, rather than spend a huge amount of time spinning the crown to advance the time. Hopefully, your watch will have the more sophisticated movement, though.
