How do you remove the Crown stick

Here are some general instructions that may help you with your watch:

1. To set the time, locate the crown (a small knob or button) on the side of the watch. Turn the crown to the right to advance the time, and to the left to go back.
2. To set the date, locate the crown and pull it out one notch. Turn the crown to the right to advance the date, and to the left to go back. When you are finished setting the date, push the crown back in to secure it.
3. The two small dials in the watch face are most likely used to track additional functions, such as a second time zone or a countdown timer. Refer to the watch manual for specific instructions on how to use these functions.
4. To activate the light-up feature, press the button or knob on the side of the watch. This will cause the watch hands and dials to light up, making it easier to read the time in low light conditions. The light will turn off automatically after a few seconds.

is this an mechanical watch? all the same open the back and look closely at the area near the crown stem. pull the crown out and see if any little levers move. If they do there may be a little indent on the lever. with the crown in press the indent with a needle and pull the crown our. the also may be a little arrow on the back of the movement pointing at a hole. press a pin in the hole and remove the crown.

Try putting (pushing) back in. Next time do not pull it too hard.

the three dials are for three different time zones, there is no minutes or seconds.
to adjust the middle dial just push the small bottom which is located on the back side of the watch

The knob that adjusts the time is called the crown, and it will have a stem attached to it. You will need to remove crown and stem together.
If it's a screw-down crown, unscrew it.
Examine the watch mechanism very carefully while pulling out the crown (as if you were adjusting the time) and pushing it back, What you are looking for is basically anything that moves. If you do see parts of the mechanism move, look very carefully around that area for an arrow mark impressed in the metal pointing to a small dip in one of the metal parts.Often, this is on a tiny lever but not all manufacturers bother with the arrow.
Ensure that the crown is pushed back to it's normal position. Put a tiny amount of pressure on the dip (a needle is ideal for this), and carefully attempt to pull out crown and stem.You may need to apply slightly more pressure to get a result, but please take care not to press too hard or you may damage the mechanism.
Hopefully, that should sort it out. To refix the numeral bar, I'd recommend super glue - but you only need a tiny, tiny amount. Apply it with the tip of a needle and you shouldn't go far wrong.
Once you're looking at reassembly, you should be able to reinsert the crown and stem without depressing the dip but do it gently and don't force it - it may need a slight turn to relocate properly before it slides back in.

I hope this was easy to follow - get back in touch if you get stuck.

I dont know why you want to remove the stem but here you go.
To remove the stem you must first loosen the set lever screw, then you can pull the stem out.
You only need to turn the set lever screw a couple turns to release the stem. Some movements use a button instead and in that case you would simply push the button down lightly with a pointed tool and while holding the button down pull the stem out.
For watches with one-piece cases where the movement comes out the dial side and the case has no removable back, you will not be able to get at the set lever screw. For this type of watch you must grasp the crown firmly and pull it out, or use plastic or soft brass tweezers to get behind the crown and pop it off. These watches have two-piece stems that have male and female ends that snap together. Then remove the bezel and let the movement come out into your hands. Then remove the hands and the dial and put the movement face down into a movement holder. Now you can remove the stem as described above

The procedure for the Classima Chronograph watch is different. You need to pull the dial all the way out, press on both buttons and hold for 5 sec, until the seconds dial makes a full cirlce (signalling that the chronograph is now ready for manual reset, then press the button on 2 o'clock until the seconds dial reaches the 12 o'clock position, then press button at 4 o'clock, to transfer control to the 1/10 dial, press button at 2 o'clock again a number of times until it resets to 0, then press 2 o'clock dial again to transfer control to the little hours dial, and press 4 o'clock button number of times until you reset this one to 0 too. Now just push back the dial crown to original position to close the operation. Viola

Pull out the crown and use either a combination or one of the cronograph buttons, this will allow you to adjust the hand positions

Your need the following tools to take out the crown...fix the hands and fix the hands.
1. Pointed Small Forcep
2. 7 or 8 no. small screw driver
You can these tools from a hardware store.
As this work is of high perecesion you need to be very careful and need high concentration.

As you have already opened the back cover of the watch you may find an arrow(--->) mark, when you press it and pull out the crown it may come out.
Now you can fix the hand by holding it by forcep and then setting it on the pinion(centre) of the dial or the position you want to fix.

In case of any difficulty you may take the watch to service centre.
