Seiko’s 40th Prospect S23627J1 Reissued!

Since the early sixties, Seiko has earned a well-deserved reputation for taking their Divers watch technology to the next level.  Seiko’s Tuna diver’s watch has become the standard for all other competitors to be measured against.

This year marks as the 40th year anniversary of Seiko’s invention of introducing the world’s first saturation diving watch with quartz movement.  To commemorate this date, Seiko has decided to release the new S23627J1 Limited Edition model watch with the same high specifications as the rest of the commemorative Tuna editions of the original 1978 model watch.  The only thing that differs from the rest is that the out case “shroud” is made from Cermet.

For those who do not know what Cermet is, it is a composite material composed of ceramic and metal that creates a material that is eight times harder than steel and it also provides a smooth glossy surface.
