This is a small, robot-shaped quartz clock. The size is approximately 4cm tall x 3cm wide. It's about the size of a postage stamp with hands, feet, and a head attached. I hadn't used it for a while after the battery died a few years ago, but it's working perfectly now that I've replaced the battery. I've confirmed that it keeps time accurately for over 24 hours. The arms rotate, and the arch connecting the ears moves. You can attach a chain to the arch and hang it from a bag, etc. 【Condition】 The surface is clean, but there are minor scratches on the back where the cap is removed (described below) (Photo 4). Operation has been confirmed. Two batteries are included as a bonus (they're cheap ones sold on Amazon, about 200 yen for a pack of 10...). 【Size】 (Measured by hand) Height: Approximately 4.4cm (without the arch: approximately 4cm) Width: Approximately 3.3cm Thickness: Approximately 1cm Weight: Approximately 31.5g 【How to Use】 ・Setting the time: Pull up the topknot on the head and turn it to move the minute hand. ・Battery replacement: You can remove the cap on the back by inserting a precision screwdriver (minus) into the upper right part (precision screwdrivers are available at 100-yen shops). ・Button battery used: LR626, SR626SW, SR66, LR66 【Package Contents】 Robot clock body, 2 replacement batteries (1 battery is used in the main unit) It will be sent via Yu-Packet Post (or similar mini). Please understand that this is a used item before purchasing. Thank you for your consideration.
