Reviews

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 for its revived, characterful design embracing '50s charm and its comfortable fit, with some finding the 42mm case size preferable to larger options. Reviewers highlight the new B31 automatic movement, noting its 78-hour power reserve and COSC certification, along with stylish Milanese bracelets and a thinner, more ergonomic case. Some owners find the watch to be the heaviest they own but also the most comfortable, with lugs that hug the wrist. However, the pared-back dive bezel is noted by some as potentially impacting legibility, and the white date wheel at 6 o'clock could be divisive. Criticism is directed at the movement at its price point by some community members, while others appreciate its quality and COSC certification. On balance, owners and reviewers rate the Breitling Superocean Heritage B31 Automatic highly for its revived design and comfortable wearability, supported by its new B31 automatic movement.

Squale 1521

Owners widely praise the Squale 1521 for its classic look and robust build, with specific mentions of its wearable 12.5mm thickness and refined case finishing. The 42mm case is noted by some to wear smaller, closer to 40mm, due to short lugs, feeling solid without being too large. However, opinions on the bracelet vary, with some finding it too flashy or stiff, and one owner reported moisture ingress after a shower due to a loose case back. The crown can be difficult to operate due to deep integration, and the 38-hour power reserve is considered old-school but reliable. Overall, owners rate the Squale 1521 highly for its classic design and wearability, despite some reservations about the bracelet and crown.
