Seiko Marinemaster "Ninja Turtle" SBBN035

Mint and unused looking condition Seiko Marinemaster "Ninja Turtle" model reference SBBN03, complete with box purchased in June 2021. It is now discontinued and this one is one of the last batch that has been made of this model. 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 in addition to the special gaskets could not allow helium to enter the watch and therefore no need for a helium escape valve for saturation diving. This presented a unique and robust professional divers watch.
