"Guess Watches Usually Take 377 or 371 Batteries"

377 batteries have many equivalents that can be cheaply purchased and tested to see if they work or not.

Thank you for contacting FixYa.
First of all, unless it is stamped or it is in the manual, I cant tell you what size battery, nor can a watchmaker unless they take measurements of the watch area.
You have a nice watch. My BEST advice is to take to an authorized Geneve watch dealer or to send direct to them (contact them first).

Nope. If it is not printed on the back of the watch, or inside, or in the manual, I have no ideal. You can try to contact GUESS at following link:

If the watch is waterproof then you need a special wrench to remove back. If it is not then you can pry the back off with a fine knife blade. You can then change the battery. Most if the time it is easier to go to a watch shop and have them put in a new battery. Usually about 5 to 10 dollars.

Your watch case back (battery cover) actually lost it shape some how that's why it's not closing, it's need alignment,
which take lots of time try expert watchmaker hope you get it fix.
even thought it fix some time it's lost capability to keep your watch save from water.
hope this info help
