What kind of battery? Can customer replace it?

I just opened the back cover using a tiny flat-head screw driver. It's using Japanese Quartz Movement MIYOTA 2115 and a common SR626SW/SR66/377 1.5V silver oxide watch battery, like this one with ASIN: B001G7PJ2A. Pull the old one out and push the new one in, put back the back cover, all done in 3 minutes. Hope this info helps.

I've seen reviews below that say the rubber wrist band breaks in a few weeks, and that the adjustment knob is made of plastic, is that correct?

I don't know about the band. But the knob broke off right out of the box when I tried to set the time. Sent it back and got another. A few months later the Knob broke off again. Do not buy this watch. Look up Smith and Wesson Lawman watch, it is a better watch and is all metal. I own one and think it is a way better watch.

How do you put the battery cover back on

It is not recommended for customers to take off the back plate or change the batteries themselves as that voids the warranty on the watch. This particular watch's back plate has to be pressure pressed on till it clicks. Make sure it is on tight and the rubber seal is placed correctly or the watch will not be water resistant.
