This is a desk clock that displays the time in a 24-hour format, showing the time in different parts of the world. The seller mainly uses it to see the time in Japan and doesn't know how to use it to see foreign times. The second hand has a small airplane attached to it, which is fun to watch move. You can adjust the time for both domestic and international locations by opening the back cover. The clock is housed in a crystal glass case that is nearly square. It seems to be a commemorative item, but the details are unknown. Although it appears to be quite old, it doesn't feel old, and the clock functions perfectly. The sides are approximately 26cm long, the depth including the stand is about 10cm, and it weighs just over 2kg. It runs on one AA battery. Please note that due to the nature of the item, we cannot accept any claims or returns after the purchase is complete.
