What people say

Owners + reviewers, side by side

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

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.

Spinnaker Fleuss 40 Automatic

Owners find the Spinnaker Fleuss 40 Automatic a good size for smaller wrists, though one owner notes the lume is too diffuse for easy nighttime reading. The pilot-style crown is an unusual feature for a dive watch. Overall, owners value the Spinnaker Fleuss 40 Automatic for its wearability on smaller wrists.

From video reviewers

The coral red dial is a unique aesthetic. The watch is a strong contender for best-in-class under $300.
