Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Breitling Superocean Heritage B31 Automatic's excellent finishing and attractive sunburst dials, with some calling it the nicest Breitling they have seen. The watch is noted for its comfortable wearability, with a mesh bracelet that hugs the wrist and a case that feels paradoxically heavy yet disappears after a few seconds. The B31 automatic movement offers a 78-hour power reserve and COSC certification. However, the design is divisive, with some disliking its aesthetic and short hands, and the use of a Sellita SW200 movement at its price point is a criticism for some. The white date display at 6 o'clock is also noted as potentially divisive. On balance, owners and reviewers appreciate the Breitling Superocean Heritage B31 Automatic for its refined finishing and comfortable wearability, with the updated movement and bracelet being key highlights.
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.
