DOXA SUB 300 BetavsSquale 1521 Classic COSC

The DOXA SUB 300 Beta is praised for its refined aesthetic and vintage charm, with a wave-patterned dial, ceramic bezel, and box-domed sapphire crystal. Owners find its 42.5mm case wears well due to its compact feel and short lug-to-lug length, making it suitable for smaller wrists and comfortable for all-day wear. The watch is powered by an automatic movement with a 38-hour power reserve. Some reviewers question the inclusion of a helium escape valve on this less tool-oriented design, and one owner notes the polished bezel is prone to scratches. Overall, owners and reviewers appreciate the DOXA SUB 300 Beta for its blend of classic dive watch appeal and modern wearability.

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.
