Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely report the Breitling Avenger Automatic's robust build and clean dial offer excellent legibility, with some finding it surprisingly wearable on smaller wrists and comfortable for daily wear. Reviewers note its streamlined, contemporary update to the collection, featuring a brushed middle case and stepped lug bevels. Owners report accuracy ranging from +1/+2 seconds per day to about -6 seconds per day, and some express reservations about the 42-hour power reserve. On balance, owners and reviewers rate the Breitling Avenger Automatic highly for its bold, bombproof design and versatile aesthetic.
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.
