Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Breitling Superocean Automatic

Owners widely praise the Breitling Superocean Automatic for its fresh design, excellent fit and finish, and comfortable bracelet with micro-adjustment. Reviewers and owners alike highlight its vibrant dials and luminous hands and hour plots, with one owner finding the blue ceramic bezel and white dial stunning in person. The Breitling Superocean Automatic has a power reserve of approximately 42 hours. Some owners find the design divisive and question the value of its ETA-based movement at its price point. One owner of the 42mm model reports theirs runs about +6 seconds per day, while a user of the 46mm model noted it ran nearly a minute fast per day. On balance, owners and reviewers rate the Breitling Superocean Automatic highly for its distinctive design and comfortable wearability.

Squale 1521 Classic COSC

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.
