This is a Seiko Chariot. It has a new, aftermarket band. The battery has been replaced, and it is running. The dial size is shown in the latter half of the images, so please refer to them. Please refer to the images for any scratches or stains, as this item has been stored personally. Before listing, I have disinfected it with alcohol and confirmed its operation, but I do not guarantee its continued operation in the future. Please understand this. This is a one-of-a-kind, used item, so I do not recommend it to those seeking the quality of a current new watch.
