SOURCE: Removing the crown/stem of CASIO EF-321

There is a tiny point (end of small metal piece called setting lever) on the left side of the stem (on watch movement, very close where the stem is entering the movement).
You have to push that point down with a metal pin or tweezers. Crown (winder) must be pushed in to normal position otherwise you will not be able to put the stem back properly.
So, do as follows:
1) Push the crown in,
2) Lay the watch down on flat surface and push on setting lever point,
3) While holding setting lever pushed in- extract the stem by gently pulling crown out of watch.
If this doesn't work- upload picture here.

SOURCE: I have a Casio AQ-47 watch. I removed the battery

This little spring is called coil spring and must be inserted in to the hole in movement. Usually there should be writing on movement with an arrow pointing to that hole. If you can not find the writing, then try to put coil spring in different holes one after another, till you hear the watch beeping again.

I have a FOSSIL mens wristwatch model # AM3423. I recently had a watch repair person replace the battery. Battery type and charge confirmed. I received the watch used as a gift from a relative who was...

Quartz watches stop working most often for one of three reasons: (1) dead battery; (2) dirt in the gears blocking the train; and (3) a bad crystal. This is the order in which I typically troubleshoot watches.

If the watch isn't working after you change the battery, first check to see that the stem is fully pushed in. A watch movement can shift just enough inside the case that a stem sometimes looks pushed in, but isn't quite in far enough to re-engage the movement. Pull out and push in the stem a few times to see if that changes anything.

Next, assuming that the battery is indeed fine, look closely at the second hand. Is it moving at all, even a tiny bit? Hold the watch up to your ear. Is there any kind of "chunk" sound about once every second? If you can answer "yes" to either of these questions, a speck of dirt has gotten into the movement and is preventing the gears from moving freely. It doesn't take more than a a big spec of dust to cause this. Sometimes, advancing the time will move the gears enough to cause the dirt to fall out. Some watch repair places also have a special machine that spins the hands rapidly to blow out or compact any dirt in the train. It's usually not economically rational to have the movement professionally cleaned beyond this point.

Finally, if you don't hear anything coming from your watch, the battery is good, and the setting stem is pushed firmly and completely into the watch movement, you may have a bad quartz timing crystal. It does happen, and when it does, the only repair is to replace the entire watch movement. Sometimes, that's affordable; sometimes, it just doesn't make sense.

Good luck!

How to remove crystal from Pulsar watch PF3142 chronograph to refit small seconds hand

There is usually a way to remove the crown and stem together so that the movement can be removed from the casing.
Have a good look over the movement and see if there are any identifying marks and let me know what you find. Alternatively, post a photo of the movement.

How can I changw the glass for this watch?

In order to replace the crystal on your watch you are going to have to remove the entire movement and use a watch press to remove the crystal.
this is not an easy job and should be done by a professional
First you will need to get a watch back opener to unscrew the back of your Tag. The three slots should fit into the back of the watch. tighten the opener until it is firmly on. then turn counter close wise until back of case comes off.
Next you will need to remove the watch hand and crown. Becareful doing this for pressing to hard will break your set leveler. You will need a thin pin pusher and look on the back of the movement for an arrow pointing toward a hole in the movement. Push down and at the same time pull the stem and crown out of movement. turn the watch right side up and the watch movement should fall out. Place movement on a very safe spot so not to damage movement or dial
now you will you be ready to remove crystal Since it is a friction crystal you will need to do use a watch case press . find two die that fit exactly the watch and crystal use a scooped side and place it on the bottom side of the watch press. Next use a flat die to place on top of the case press. place the watch face down. you will be pushing the watch crystal out from the top. Press down on the level and check to see if the crystal came loose, keep doing so till the crystal comes out.
finally you will need to measure the thickness and diameter of the crystal and find the exact size. I believe this watch has a sapphire crystal so you will need a sapphire crystal too.
Once you buy the proper crystal it is time to put the it in the watch. Place the watch face up in your watch press. and slip the crystal in through the top making sure its perfectly even all around. Slowly push down on the leveler until proper pressure is applied and the crystal snaps in.
Now you have new crystal . Clean crystal thoroughly and the inside of the case. Place watch upside down carefully place movement back in. slide spacer in . Now slide watch stem and crown back in push down again on the set leveler with pin pusher.
Place case cover on back and tighten properly to prevent water or moisture from entering and you are done.
This repair should be done by a professional especially on such a nice watch. Any watchmaker can do this job and will have the tools to do it properly

I have a ladies Philip Stein, w, double movement. Tried to buff crystal. Now neither movement is working. Batteries are OK

If the stems are in the time positon and the batteries are ok what probably happened is extreme heat. You tried to polish a mineral crystal and it got hot. The only type of crystal you can polish is acrylic. Most of these models come with mineral crystal or scratch proof sapphire crystal. I recommend going to a watch maker/technician and having the movements replaced. A reputable watch maker/technician will be pretty reasonable.

The analog portion of my Casio watch has a problem. The hour hand is lagging. Ex at exactly 3:00 the hour hand will not be on 3 it will be at about the 14 minute mark. Can you help? I recall my Citizen...

You will need to remove the crystal, but without proper watchmaking tools and skills you will not be able to do the job. If you do not want to damage your watch, you have to find your nearest watch repair shop and ask to fix it.
