Thank you very much for viewing. This appears to be a vintage Swatch model. It's an aluminum watch. It's a simple digital watch. However, it seems to have a full range of features, including a chronograph and backlight. It came with instructions in a foreign language, so it's likely a stock item for an overseas model. The battery has been replaced with a new one, and I was able to set the time and other intuitive functions. It was clean, but I have cleaned the entire watch. The band is spring-loaded, and the inner circumference is about 16cm when not stretched. This spring-loaded band refers to the inside of the buckle, and the band itself is fixed. Considering the length of the band, it may be classified as a fashion watch for women. The outer diameter is about 47mm, and the thickness is about 20mm. I think it will definitely stand out when worn as an interesting watch. It is clean, but it is a used item. Thank you for your understanding of used items.
