Aquastar Benthos Heritage IIvsSquale 1521 Classic COSC

The Aquastar Benthos Heritage II is widely praised for its significantly improved wearability due to its 40mm case and reduced thickness, noted as 12mm by one source and 11.9mm by others, making it comfortable on smaller wrists. Reviewers and owners appreciate the scaling down of a classic design while retaining key elements, with the sapphire crystal and the manually operated helium release valve (HRV/HEV) being highlighted, the latter sometimes described as a "fidget aid." The watch is considered a fantastic value at its pre-order price of $1,190 on a rubber strap. Some owners miss the dial depth of earlier models, and the dual-crown design with the HRV is seen by some as a stylistic compromise. On balance, owners and reviewers rate the Aquastar Benthos Heritage II highly for its comfortable wearability and excellent value at the price point.

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.
