CWC Quartz Divers Watch Mk.2 Polished Case

The CWC Quartz Divers Watch Mk.2 Polished Case is praised for its excellent case finishing and a perfect 120-click bezel, with significantly improved lume over previous versions and a sapphire crystal noted as a welcome upgrade. One owner noted a disappointing mark in the case polishing, stating that other watches at half the cost exhibit better overall finishing. The polished case is true to the original but seems odd for a military homage. Overall, owners rate the CWC Quartz Divers Watch Mk.2 Polished Case highly for its case finishing and bezel action, despite some concerns about value proposition and polishing quality.

Lum-Tec Solar Marine

Owners widely praise the Lum-Tec Solar Marine for its all-black diver design, excellent lume, and rugged, tank-like build. This 39mm watch is noted as a great smaller option, fitting a 7-inch wrist perfectly and suitable for extensive water activities. One owner cautions that the PVD coating may wear and chip within a year. On balance, owners rate the Lum-Tec Solar Marine highly for its rugged build and excellent lume in a compact dive watch package.
