Why you'll like it

The Seiko Prospex SRP789J1 combines the iconic cushion-shaped Turtle case with one of the model’s most recognizable colour combinations — a deep black dial and red-and-black “Coke” bezel. Its substantial stainless steel construction gives it classic professional-diver character, while strong LumiBrite visibility and the reliable 4R36 automatic movement make it highly practical for everyday wear. With 200-metre water resistance and the desirable Made-in-Japan J1 configuration, it is also an appealing choice for Seiko enthusiasts looking for an older Turtle reference that is becoming harder to find new.
