This item is a Seiko Third Diver from 1979. Model number: 6306-7001. It was overhauled at a watch store in December 2025 (Reiwa 7). The bezel disc and glass were replaced during the overhaul. The strap is not included. It's a cool watch. The Seiko Third Diver is popular both overseas and domestically. Please refrain from purchasing if you are sensitive to scratches or wear. This watch looks great with both suits and casual wear. Thank you. We also have many other items for sale, so please take a look. Please note that we do not accept cancellations after purchase.
