Nice little wrist watch, Citizen GN-4W-S S046947 with minor scratches on the back. I had it in a drawer for a few months and, for some reason it stopped working. I thought it could have been the battery so I took it to a local jeweller who told me the battery is still new but the watch isn't moving and it would need to be sent to Citizen to find out what the issue is, action that would likely cost more than its value. 
Other than that, the watch looks practically new and it comes with a Citizen box but it's not the original one.
