What people say

Owners + reviewers, side by side

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

Breitling Superocean Heritage B31 Automatic

Owners widely praise the Breitling Superocean Heritage B31 Automatic's revived, characterful design with '50s charm and its comfortable wearability, with some noting the lugs hugging the wrist and a massaging mesh bracelet. The new Breitling B31 movement offers a 78-hour power reserve and COSC certification, and the 42mm case size is preferred by some over larger variants. Reviewers and owners note the pared-back dive bezel may impact legibility, and opinions are divided on the white date wheel at 6 o'clock. Some find Breitling watches, including this model, too large or chunky for smaller wrists, and criticism is directed at the Sellita SW200 movement at its price point by some owners. Overall, owners rate the Breitling Superocean Heritage B31 Automatic highly for its comfortable wearability and revived, characterful design.

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.
