How can I change the time and date on my wife's Rolex? The stem will pop out but nothing happens when I turn it either way. No change of date or time.

Pull the right post out. It may first have to be unscrewed to unlock it. Pull it out one click to set the date, two clicks to set the time. I recommend setting the time first and go all the way past 12 to see if you are on AM or PM (the date will advance or won't). Set the time correctly, then push the stem in one click and set the date. Push the stem in all the way and then turn it to wind. You can't over wind an automatic watch but always use gentle pressure to avoid damage.

The Rolex time change is done after three clicks when you pull the winder. If the winder can actually be pulled out of the stem (separate) the damage is serious.
Sorry. Only an authorized dealer can get the parts for it to be repaired.

A standard ladies rolex should have just one stem and crown on the side. Occasionally the crown is a screw down crown. Try to pull the crown out if it does not pull out try to pull and unscrew it at the same time. There are two settings one you pull the stem all the way out and that should set the time, if there is a day or date setting, you push the stem halfway in turn one way for day and other way for date. Please let me know if there are any other buttons on watch thank you!

1)Unscrew the crown until it pops out, the same way you would unscrew the crown to change the time on the watch.
2)Place the watch case opener in the notches around the outside of the back of the watch case. You have to use a watch case opener made for Rolex watches to open the watch. Once the case opener is in place, twist it and the back will pop open.
3)Use a mini screwdriver to loosen a tiny screw on the inside of the watch located near the stem. You do not need to unscrew fully--only loosen it.
4)Pull the crown straight out. The crown and stem should come out easily.
To open the back of the watch
1)Purchase a Rolex watch back opener set, if you do not already have one. This set is able to open and close any size of Rolex case.
2)Match the size of your Rolex case with the same size of grooved metal die from the tool set.
3)Put the metal die on the grooves on the back of the watch case.
4)Turn the die to remove the case.
5)Remove the rubber gasket.

The stem has 2 settings...the first pull[click] will be for time only. then pul lit harder and it will come out a little farther and you set the day and date.. Christmas or B-Day ...Congratz..

There isn;t any downloadable manuals for Rolex watches, but operation of Rolex Day-Date is very simple:
1) when you unscrew the crown, it is in winding position,
2) when you pull out the crown to the first click, it is in day and date setting position (depending wich way you turn the crown).
NOTE: to adjust the day or date, previously you have to advance hands forward, passing 12 o'clock (midnight) mark and stop advancing at 4.00 a.m. using the crown in position as described in chapter 3. When done - push the crown fully in, then pull out to the first click and only then adjust the day or date.
3) when you pull the crown further out to the second click, it is in time setting position.
To find the daytime or night time on the watch: pull out crown to the second click and advance watch hands forward till you pass the 12 mark on dial. If the date changes as you pass it - it is the night time (midnight). If the date do not change as you pass it - it is the daytime (noon).
After all settings being done, allways screw the crown back down as it protects the watch from water and moisture.
Never use watch in sauna- it's not designed for that.
Do not forget to rate, please.

Usually to change the date you need to have the crown pulled out to a position that is between the "closed" position and the position where it will move the minute/second hands.

1) un-screw the pin by turning it towards you, until the spring pops it out. 2) pull the pin out to the next notch 3) turn the pin towards you and watch the date change (if the minute hand is moving when you turn the pin, you pulled out too far).

There are three positions when you unscrew the crown stem. One does the day, one does the date and one does the time. You can also advance the date by rotating the crown stem and advance the time for 24 hours, as if a day passed. That takes a lot longer.  

try this: remove the stem (I assume you got the stem back on). borrow a strong shop vacuum and literally suck the moisture out the hole using your hand or duct tape tightly wrapped to funnel the vacuum from the tiny hole.
