You should be able to pry it off, just follow this simple steps:
Locate a very small tab (or recessed area) on the edge of the back cover. Pull out the stem, which releases the back on some watches.Get a small flathead screwdriver it needs to be a thin inflexible tip. Very carefully slide the blade under the tiny metal protrusion on the back cover (or across the length of the recessed area, depending on which type of cover your watch has). When you replace the cover, make sure you line up the stem slot on the cover with the stem of the watch. These steps are listed on wikihow:

These babies are notorious for going down the tubes with a battery change. I bet if you get it back it won't work with a new battery. Twice I have replaced batteries and the watch didn't work when I finished. One of them was my own watch, I think $450 is about half the price of a new watch and that is sad. Cool watch just not very long life

If you changed battery yourself, you've lost the tiny spring without noticing it. Carefully check around the place where you changed the battery. The spring itself is very, very tiny, so, be as concentrated as much as you can. That spring (coilspring named by watchmakers) transmits the signal from watch movement to the watch back cover where the sound membrane is located. In case if you find it, open the watch and insert that spring with the bent out end first in to the desired hole in watch movement (should be named COIL SPRING). After that re-assemble watch and the sound should work.

mcdevito75 here, Just had the battery changed, if the watch was running fine before the last battery died, and now with this battery change the watch can"t keep time, try another battery as any Battery can be weak just from storage.

Best not to change it yourself...you might be able to open the watch but can you close it? Thats where people run into trouble and end up breaking the crystal! :-) Find a reputable watch repair shop and let them change your battery!

If the watch is running try to sync the watch 1st, meaning set the minute and hour hands pointing to 12:00 o'clock. before you go to set the time.
