Vintage 1968 Seiko Five Sport Diver 6106-8120 Serviced Original JDM
Presenting the iconic and ultra cool Seiko 5 Sports “Diver,” a 25-jewel automatic watch made in August 1968. Just serviced and in fantastic condition, it’s ready for many more years of wear. This original piece was the inspiration behind the popular 2023 limited edition reissue, the SRPK17.
Originally launched in 1968, the Seiko 5 Sports line was designed for an active lifestyle, offering durability and style for the young and adventurous. This model is powered by the caliber 6106A (the base caliber for Seiko’s 61GS), which is in excellent condition after a full service, running accurately and reliably.
This watch remains in its original, unpolished condition. The Original bezel is well-preserved, rotates bidirectionally with ease, and is complemented by the original bezel insert, also in great condition. The dial and hands retain their original lume and show beautifully. It comes fitted with a vintage bracelet (20.5cm overall length), enhancing its classic appeal.
Please take a close look at the photos and videos, as they provide a detailed view of the watch’s condition.
A Note on Vintage Watch Ownership
Vintage mechanical watches are robust and reliable, but they are not as accurate as modern quartz watches and require periodic servicing. Some signs of age and natural patina should be expected and are considered part of the character of an original vintage timepiece.
At TEMPO PRIMA, we believe original watches should be preserved rather than restored. We do not pressure-test vintage watches and therefore cannot guarantee water resistance, regardless of their original specifications. For their long-term preservation, we recommend keeping all vintage watches away from water and excessive moisture.
