This is a solar-powered watch. It's working properly. I received it 12-13 years ago and used it for about 5 years. After that, I stored it without using it. There are no major scratches, but there are some minor ones. There are no size adjustment clasps. I measured the inner circumference of the watch, and it was 15cm. Please purchase if you understand that this is a used item. EO31 R004581 #wicca #wristwatch #solarpoweredwatch
