No the face is not scratched it has plastic over it, and No the band is not worn far as I know it has never been wore , and the battery is a reg. watch battery , I am not taking the pens out to get to the battery sorry.
I took out a pin like I did not want to do and the only numbers I seen are hard to read but there is a JR9018 and 250829 I am not sure of the last set of numbers but that is what I got and the back has a scratch on it even though it has plastic over it also. I also added another pic. of the back, And you are welcome.
