Reviews

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

CWC E9 Automatic Diver

Owners widely praise the CWC (Cabot Watch Company) E9 Automatic Diver Watch for its classic dial design, excellent lume, and exceptionally durable PVD-coated case that withstands rough use. Reviewers note the 41mm case wears close to perfectly, with a modest 12mm thickness. One owner suggests replacing the mineral crystal with sapphire to prevent scratches. On balance, owners and reviewers rate the CWC (Cabot Watch Company) E9 Automatic Diver Watch highly for its legible dial 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.
