* Case approx.: 21x28mm * Thickness approx.: 6mm * Belt size: 180mm, Width approx.: 16mm Currently, the prices of square-shaped watches in general, including the Cartier Tank design, are soaring. To solve this problem, we propose several models from other famous brands that offer high quality and similar designs at a more affordable price. We hope you will consider them. The leather strap and battery have been replaced with new ones, so you can purchase and use them with confidence. The dial has a unique and very popular finish that is characteristic of SEIKO. The square case with Roman numeral dial has a size and design similar to the Cartier Tank SM size. * There are some sellers who list non-working, "junk" items as "battery dead" or "operation unconfirmed" to give the impression that they might work. Most of the time, they do not function properly, so please be careful. (We provide information after confirming normal operation and performing internal maintenance.) * As this is a vintage item, battery replacement, repairs, or overhauls may be necessary in the future. Also, this item is not recommended for those who are sensitive to the condition of vintage items, such as scratches and dust. * To avoid fraudulent activities related to repair costs and parts replacement, we do not accept returns. We also do not respond to any claims after purchase. As this is a used item, even if waterproof performance is stated, we recommend not exposing it to water. We are not responsible for any water damage that may occur, so please understand. By clicking the purchase button, you agree to all of the above conditions. * Also, this watch is also sold on other sites. If two people purchase it at the same time, we will ship it to the person who paid first, so please understand.
