Yes, it has a Swiss Quartz movement, so a battery is what makes your watch work. Need a new battery? Take it an authorized dealer or other business that has the right tool to open the case. It's not worth ruining an expensive watch just to save a couple of dollars to change the battery.

good day,
hope this link below will solve your problem.

The day is changed when the watch passes midnight or thereabouts. Turn the winder until the date changes and then turn it backwards until it is past the date changing point and wind it forwards.

You will have to experiment to find how far back you need to turn it before going forwards again.

Any jewler who handles Swiss Army can help you

Save yourself the time and frustration and take it to a reputable watch repair shop and let them adjust your band for you. Could be screws or could be pins! Plus if anything small drops you might not find it again!

There is a tool that you need that adjusts to the three holes or openings in the back of your watch and it just screws off. If you don't have access to the tool, simply take two push pins and CAREFULLY insert them into the openings and unscrew the back cover. Remember that it unscrews counter-clockwise.This will give you access to the battery simply take it out and go to the store to buy a replacement repeat the process to install the cover back on.
