Antique-style pocket watch pendant The back opens, allowing you to replace the button battery. It should work with a new battery, but I haven't tested it, so I can't guarantee it. I have not confirmed its operation. There is a small scratch near the number 2 on the dial cover. Press the knob on the top to open the cover. Why not coordinate it as a small interior item? Please refrain from purchasing if you are sensitive to used items, as this is a home-stored item. Shipping will be via Yu-Packet Post or Nekopos. Body size: Approximately 4.8cm Chain length: Approximately 70cm when fully extended
