Didnt test it , my tool dont have the right range to open the back case to test it , the back case is too big for it. The watch will sell as for parts or repair. The watch has broken insert bazel (the green glass inside the bazel). The strap has visible damge on one side , the other side looks pretty much in good condition. Dont know if the watch is working , it can work. Please see photos to underdtand condition.
