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 Classic COSC's well-proportioned 42mm case, with one reviewer calling it a masterclass in case design. The COSC certification is noted to improve accuracy, and the bezel indices are now fully lumed, a feature some owners find superior. The brushed case with polished chamfers is described as a significant and attractive aesthetic update. However, some owners prefer older bezel designs, and opinions on the lume are mixed, with one user finding it only "okay." One owner reported moisture ingress after a shower due to a loose case back on a new watch. The Squale 1521 Classic COSC is priced at CHF 1,475 and uses a Sellita SW200-1 movement. Overall, owners rate the Squale 1521 Classic COSC highly for its updated finishing and improved accuracy.
