Harry Potter Goblet of Fire Triwizard Maze Limited Edition Watch #HC0416

This is brand new. Never worn. Still has plastic on dial on both sides. The only thing showing wear and tear is the pillow it’s been wrapped around for years basically disintegrated. Never worn and obviously battery is dead. Don’t know if it will work with a new battery because I didn’t want to open it. This is extremely rare limited edition. There were only 1000 made. This one is numbered 792/1000 engraved on the back.
