Thank you for viewing from among the many products. ABOUT VINTAGE 1815 Chronograph Since it has been worn only a few times, I think it can still be used. The battery was just replaced at a watch shop, and it is working properly. Please check the condition in the photos as there are scratches on the back. There is no box or instruction manual. This is an item for sale with the main body only. You can purchase it as is, or you can leave a comment. Thank you.
