Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Owners widely praise the DOXA SUB 300T's functional and distinctive design, with reviewers highlighting its historical visibility and robust build. Legibility is consistently noted as excellent, with reviewers appreciating the functional no-decompression bezel and distinct hand shapes. The watch's accuracy is reported as good, with one owner seeing a 3-4 second daily gain, though the 38-hour power reserve is considered underwhelming by some at its price point. Criticisms include a stamped clasp that feels out of place and a bezel that may have lateral movement. The 42.5mm case is described as substantial and heavy, appearing larger due to extra width and making it unsuitable for dress shirts, a trade-off for its 1200-meter water resistance. On balance, owners and reviewers rate the DOXA SUB 300T highly for its unique design and robust dive watch capabilities.
