The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition (ref. spb301j1) is an automatic diver watch, with a 42.7mm stainless steel case, 13.2mm thick, powered by the 6R35 movement and a 70-hour power reserve. Water resistance is rated to 200m, under a sapphire crystal. Manufacturer MSRP is $1,350.
The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.
