This is a wall clock designed with motorcycle tires and wheels. I determined it was designed with motorcycle tires and wheels because the center part of the tire is raised. The clock's operation has been confirmed with one AA battery. As it was installed in a garage, there are signs of use, scuffs, scratches, dirt, and tears. Notably, there are scratches concentrated in the center, making it cloudy. There is also a tear near the 12 o'clock numeral, caused by the wall-hanging hook being inserted from the back. Additionally, the grooves of the surrounding tire have dust and other dirt. I removed the front panel and wiped off dust with a brush, but some remains. There are also scratches from this process. The size is approximately 35.5 cm in diameter and 7.7 cm in depth. While operation has been confirmed, I cannot guarantee the accuracy of the timekeeping, nor can I predict when it will reach the end of its life, so please no complaints regarding these points. Also, it makes a "ticking" sound, so it may not be suitable for bedrooms, etc. Please use it in places where the sound is not a concern, such as a garage. There is a box on the lower back with a female DC power socket. I initially thought it might be for an alarm, but there is no speaker or switch. I also considered if it was for a light function, but there is no "V" or other voltage indication, so I believe it is not for a light and is unusable. Also, the area marked with "+" and "-" is cracked. Please check the images. If you have any concerns, please refrain from purchasing. Only the main unit is included. Batteries, wall hooks, instruction manuals, original boxes, power adapters, and other accessories are not included. A measuring tape is also not included. We are looking for someone who understands this.
