Mint and barely used looking condition Seiko Marinemaster nicknamed Emperor Tuna reference SBDX013 . This is a Japan only market model so difficult to get elsewhere in the world. Seiko Tuna is the name given to Seikos range of watches designed for scuba and professional diving. In particular. Seiko made these watches with saturation diving or greater depth diving in mind. All of the watches in the Seiko Tuna range are characterized by protective screwed on shrouds that have earned them the nickname of Tuna.

This presented a unique and robust professional divers watch.
