Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition for its attractive, well-made design and gorgeous dial, noting its jewel-toned teal color and rippling-water pattern. The bezel action is smooth with a muted sound, and the case and bracelet offer a more comfortable feel than previous iterations. However, multiple owners express disappointment with the accuracy of the 6R movement at its price point, with some noting theirs runs slow, and consider the price too high. The steep rehaut and marker size make the 24-hour numbers difficult to read, and some find the case design makes the watch feel top-heavy despite wearing smaller. Overall, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition highly for its striking dial and refined case design, despite concerns regarding movement accuracy at its price.

Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition

Owners widely praise the Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition for its unique dial color and execution, with one owner noting its 44mm lug-to-lug measurement is perfect for most wrists. The dial is inspired by Okinawa's ocean colors and is expected to feature a bright sunburst effect. Accuracy figures for the 6R35 movement range from -10/+10 seconds per day when off/on the wrist, which some find "pretty amazing." However, some owners consider the price of around 1500€ too high, suggesting a value closer to 900€, and there are mixed reports on the 6R movement's accuracy. Overall, owners rate the Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special Edition highly for its distinctive dial and wearability, despite some reservations about its price point.
