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 62MAS

The Seiko Prospex Sea 1965 Heritage Diver's Watch is praised for its vintage-inspired finishing, crisp bezel action, and build quality. Owners widely report the movement averages within +/- 10 seconds per day, though some note accuracy issues. The 40mm case size is considered by some to wear larger than expected, and the price point is a subject of debate, with some finding it too high and others fair. The watch features a 72-hour power reserve from the Caliber 6R55 movement, a 300-meter depth rating, and a box-shaped sapphire crystal. On balance, owners and reviewers appreciate the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined design and solid build quality, despite some reservations about its price and perceived size.

From video reviewers

The 37.5mm-38mm case size is a significant strength, offering a historically accurate and comfortable fit. Reviewers did not agree on any specific weaknesses.
