The Seiko Prospex SBDC197 (SPB453J1) is a 40mm stainless steel automatic diver built on the 1965 Seiko diver design. It runs the 6R35 movement with about 72 hours of power reserve and adds a GMT function for tracking a second time zone. It suits people who want a compact, everyday-wearable dive watch with real heritage behind it. Against larger 44mm Prospex divers it wears smaller and dressier, and against Swiss divers at similar positioning it offers more features for the money, though its accuracy is factory-rated rather than chronometer-grade.

Owners rate it highly, at 4.5 out of 5 from 13 ratings. They like the compact case, the long power reserve and the heritage styling. Some note the movement's timekeeping varies more than a precision-grade watch.
This Seiko Prospex diver's watch is based on the 1965 Seiko Divers, the first diver's watch released in Japan. It has a modern design and a 40mm round stainless steel case with DiaShield. The dial is black, with a silver-tone metal band.
It uses the Cal.6R35 automatic movement, which can also be wound by hand and has a GMT function. The power reserve is approximately 72 hours. The case is water resistant to 300m for diving and has a unidirectional rotating bezel and a screw-down crown and case back. LumiBrite is applied to the hands, indexes and bezel.
The crystal is curved sapphire with an inner anti-reflective coating. The band has a one-push three-fold clasp with a double lock and a diver's extender. The watch is made in Japan.
