Reviews

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

CWC RN81 Clearance Diver Automatic Watch

Owners widely praise the CWC RN81 Clearance Diver Automatic Watch for its build quality and comfortable wear, with some appreciating the fixed springbars and historical significance as a tool watch. However, reviewers and owners note the "faux patina" lume color is considered too gold and glossy, and some find the polished case and dial text/logo less appealing. The CWC RN81 Clearance Diver Automatic Watch is also seen as overpriced by some, with concerns raised about the acrylic bezel's durability and import taxes for US buyers. On balance, owners and reviewers value the CWC RN81 Clearance Diver Automatic Watch for its faithful reissue design and historical connection, though price and specific aesthetic choices are points of contention.

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.
