Unused pocket watch featuring a rare National Police Agency emblem (English inscription)! I believe it takes a battery, but I haven't confirmed it's working! I think it will work if you replace the battery. The back says "metal," so it's probably gold-plated! The size is about 4cm including the crown! Please note that the box has a slight crease as shown in the last photo! I don't know much about the watch itself, so please understand that it's non-refundable and non-returnable! As a bonus, I'll include a National Police Agency telephone card! The photo on this card shows the former National Police Agency building from two directions! (It's the building of the former Ministry of Home Affairs, the highest authority in the country!) Some people may find this more valuable (both cards are unused!)
