Seiko’s history is packed with important watches, such as the 1965 62MAS (the brand’s first dive watch), the 1968 Hi-Beat Automatic Diver 300m, and the 1970 Turtle watch.
Seiko has long used these historical models to create modern watches reissuing vintage design cues. The new SPB313J1, SPB315J1, and SPB317J1 are again part of these models, with a design that feels rather retro-inspired, for a good reason. This model takes inspiration from a 1968 watch, the rather confidential 6105-8000 Automatic Diver, successor to the legendary 62MAS.
