Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition for its beautiful design and refinement over prior models, with its glacier-inspired textured dial being a particular highlight. However, a significant portion of the community finds the €1500 RRP to be too high, suggesting a price point closer to €900-€1000, and note the use of an aluminum bezel insert. Some owners report that the 6R movement runs slow. On balance, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition highly for its aesthetic refinement, though the price point is a notable concern for the community.
