Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners praise the Laco Köln's Type B dial for legibility and lume, with one owner finding the manual winding feel superior and noting consistent accuracy of +2.5 seconds per day. The timing bezel is considered practical. However, the 49.5mm lug-to-lug and male end links make the 41mm Laco Köln too large for wrists smaller than 6 inches. On balance, owners value the Laco Köln for its legible Type B dial and practical bezel, despite its substantial lug-to-lug measurement.
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.
