Reviews

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

CWC RN Quartz Divers Watch Mk.2, Matte Top

Owners widely praise the CWC RN Quartz Divers Watch Mk.2, Matte Top for its matte finish, precise seconds hand alignment, and old-school dial and hands reminiscent of vintage Omega. The Mk.2 upgrades, including a sapphire crystal, improved lume, and a precise 120-click bezel described as "perfection," are consistently highlighted. Some owners consider its toolish design and comfortable 11mm thickness a significant draw. However, a few find the £700-£900 price point high for a quartz watch, and one owner reported chipping on the PVD finish after a few months. One owner also noted the Ronda 517 quartz movement gained 8 seconds over several months. Overall, owners rate the CWC RN Quartz Divers Watch Mk.2, Matte Top highly for its robust, military-inspired design and significant Mk.2 upgrades at the price.

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.
