Seiko Tuna is the name given to a range of watches designed for scuba and professional diving. In particular, Seiko made these watches with saturation diving or greater depth diving in mind.[1] All of the watches in the Seiko Tuna range are characterized by protective screwed-on shrouds that have earned them the nickname of “Tuna”.[2]

The Seiko Tuna series covers four main movements: 6159B, 7549A, 7C46, and 5M23. The first was the 6159B movement, which is also called the “Grandfather Tuna.” It was followed by the 7549A and 7C46 movements, which are both called “Golden Tuna” due to the distinct gold tint in their shrouds. Lastly, the youngest in the series, 5M23, is aptly called “Baby Tuna.”[1]

The Seiko Tuna range boasts of many firsts. The range was the first to feature a ceramic-coated titanium shroud, a titanium monocoque case, an L-shaped gasket, and a vented rubber strap.[1] Primarily built for functionality, the Seiko Tuna watches can withstand great depths as tools for professional divers.
