Seiko Prospex Sea 1965 Heritage Diver's Save the Ocean Special EditionvsSpinnaker Spence 300

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.

The Spinnaker Spence 300 is widely praised for its slim 10.9mm case and 40mm diameter, offering a comfortable and uncommon thin diver design at its price point. Reviewers and owners highlight its value, especially below $350, and its blend of retro design with modern specifications, including a 300m depth rating and a fully indexed bezel. Some owners, however, find the dial printing and bracelet finishing to be less refined, with one noting the bracelet's male end links as a drawback. The consensus is that the Spinnaker Spence 300 is highly regarded for its exceptional value and wearable dimensions, making it a strong contender for an everyday sports watch.
