Owners + reviewers, side by side

CWC RN Quartz Divers Watch Mk.2, Matte Top

Owners widely praise the CWC RN Quartz Divers Watch Mk.2, Matte Top for its excellent matte case finishing, precise seconds hand alignment, and dial reminiscent of vintage military watches. The Mk.2 upgrades, including a sapphire crystal, improved lume, and a precise 120-click bezel described as perfection with no play, are consistently highlighted as significant improvements over earlier versions. One owner noted the quartz movement gained 8 seconds over several months. Overall, owners rate the CWC RN Quartz Divers Watch Mk.2, Matte Top highly for its solid construction, military significance, and terrific value.

Spinnaker Piccard

Owners widely praise the Spinnaker Piccard for its comfortable wear, excellent readability, and bold, vintage-inspired design that redefines dive watch aesthetics. However, some owners view the Spinnaker Piccard as a specialty novelty watch, describing it as huge and heavy with a large crystal that hinders legibility, making it an acquired taste. On balance, owners find the Spinnaker Piccard to be a unique dive watch with a distinctive design, though its substantial size and crystal may not suit all wearers.
