It's been left untouched for many years. I recently put in a new battery, and it works, but the analog hands seem to be running a bit fast... Those who don't pay close attention might not notice. It also has a digital display, so it's difficult to get the digital and analog displays to match perfectly. The stopwatch function works normally. The backlight also illuminates. The bezel cover is missing, so the appearance is quite different from when it was new. It was originally partially disassembled, and I replaced the battery myself, so I don't think the water resistance and atmospheric pressure functions have the same specifications as when it was new. Dust might also have gotten inside. So, it's working, but there are various issues. #AW570 #Gshock #Casio #Mudman
