Purchased at a Sanrio shop and attached to a plushie. The battery is dead, so operation is unconfirmed. Please prepare or replace the battery yourself. Also, this is an old item. Please understand this before purchasing. Part of the circular ring has a rusty color. Also, the plated parts of the watch have an overall worn feeling. The back film has not been peeled off, so it should be clean. Please check the photos. Size: Watch part 2.8cm long, 2.8cm wide, necklace part 38cm
