mcdevito75 here, This can be a problem, the tolerances between the back cover and case of the watch is in MM. Believe it or not here"s a trick you can try, place the cover only in the frig. for a 1/2 hour, the cold frig. may and should shrink the back cover just enough to fit back onto the caseing. Also make sure you have any cutouts or indentations on the back cover matching anything on the case of the watch, one thing is the cutout for the winding stem of the watch, there should be a cutout on the back cover for the stem of the watch.

After much frustration, I found the solution...
Push the set button while on time mode. Push mode until the hour is flashing.Push Split/Reset.
That should be your solution!

I had the same problem and tried everything. Here was my solution. Use a double-sided 2" rubber mallet. (Below is a photo of a similiar mallet.) Be sure to use caution while pressing with force. There is always the danger of cracking the crystal, however, my solution worked perfectly for me. I hope it does for you, too. Keep in mind that some watch backs screw on with a special tool, but if you snapped yours off, it should snap back on.

  1. Place one of the rubber mallet heads over the watch back.
  2. With all your force, push down on the other end of the mallet's head.
  3. Voila, you should hear a slight pop and the back will again be secure on the watch.
Hope this helps and you are as successful as I was with this tip.

  1. First, find the regular time mode by pressing the MODE button until the time (with the date at the top) shows.
  2. Press & hold the SET button until the word ENTER disappears and is replaced by the word TIME. Release that button. You'll notice that at the top of the display, the words SET T1 or SET - T2. This is where you select between setting the 1st time zone or the 2nd time zone. Select between T1 or T2 by pressing the RECALL button or the STOP/RESET button.
  3. Press either the MODE or the START/SPLIT button. You'll notice that whatever is blinking is what you can change. You can make the changes by pressing either the RECALL or the STOP/RESET button. You can change the Seconds, the Hours, the Minutes, the Month, the Date, the Year, and choose between 12 hour (civilian) or 24 hour (military) time. If you keep MODE or START/SPLIT button, you will go through all the things you can change and start again at the beginning. The START/SPLIT button goes through these things forward, and the MODE goes through the backwards, so if you pass something and want to back up, just switch buttons. In the same way, the RECALL changes things by making them larger, and STOP/RESET changes them by making them smaller, so if you accidentally pass the number you're trying to set it to, just switch to the other button and go back.

  2. Place one of the rubber mallet heads on the watch back.
  3. Apply pressure on the other end of the mallet's head. (Don't hammer it!)
  4. Voila, you should hear a slight pop and the back will again be secure on the watch

The rubber mallet distributes the weight evenly across the diameter of the watch back and it gives you more leverage when you push down on it. It worked great for me! Good luck!

Align the caseback exactly as it was before you opened it. Make sure thet the groove for stem is in correct position. Lay the napkin on the flat table surface, put the watch on it (dial down) and using both hands and your body weight push the caseback down back in place. Remember: the side of the caseback wich first came out must be last pushed in.
Do not use very soft napkin (towel) as this can brake the glass under the pressure.
If all above described DO NOT work, then there is not enough power in your hands or not enough weight in your body and you will need watchmakers help (he/she will be using special watch press to close the watch).
P.S. Do not get upset if you can not close it; I'm very expierenced watchmaker and very often came across the watches wich I was not able to close without the watch press (even my arms are quite strong and the weight is 95kg).

Do not forget to rate, please.

I used to work with jewelry. !!BEWARE!!
This method is for face crystals that are completely FLAT! Any convex crystal will shatter without proper tools!!!
Any method of putting the watch cover back with the watch remotely near water/moisture is a mistake. The watch will rust sooner or later.
So if you don't want to pay a jeweler five dollars to put it back on, this is what I did to my sister's watch cover when I could not snap it back.
I took my cushy 1/4 inch mousepad to a vise. You may not have a vise. If you don't, stop reading now and take the watch to a jeweler --one who replaces batteries.
Inside the vise jaws, I used a 5 inch square piece of wood, then my cushy mousepad, then the watch facing the pad, then the back in the right place for restoring.
!!!!NOTE: Not having the back in the right place will smash the stem and damage can/will result!!!
To push the back on, I picked a 12 point socket out of my socket set that was the same DIAMETER as the watch back and placed it CENTERED behind the back.
Recapping, inside vise:
  • small board
  • cushy mousepad (to avoid scarring and crystal breakage
  • watch crystal facing mousepad
  • watch back in correct position
  • ratchet socket the same diameter as watch back centered behind cover
Slowly I positioned all these items with minimal pressure. Then when I was sure that I was ready (and prepared to hear the crystal break) I put as little pressure closing the vise that I could. The I heard a snap, and to my relief, it was the back going in!

I DO NOT RECOMMEND THAT YOU DO WHAT I DID. People with broken watch crystals become very IRATE when "all it needed was a battery"!

A screw clamp would also give adequate pressure. Any unsupported direct pressure over the crystal will shatter it!

Hope this helped.
Good luck!!!!

Back either:
1. Snaps off. You need a watchmakers press to get it bacl on
2. Screws off. You need a crab-claw type wrenct to remove.
