What people say

Owners + reviewers, side by side

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

CWC G40 Sonar Quartz Watch

Owners widely appreciate the CWC G40 Sonar Quartz Watch for its classic G10 design, 40mm case size, and 20atm water resistance, noting its light, rugged, and reliable "grab-n-go" nature. Some find the dial proportions have too much negative space, while others praise its unique anodized red crown and quality NATO straps. A larger crown can dig into the wrist, and the lack of a battery hatch is a trade-off for its 100m water resistance. On balance, owners value the CWC G40 Sonar Quartz Watch for its robust build and classic aesthetic, though its price point and competition are frequently cited concerns.

CWC Automatic Divers Watch Mk.2 Black

Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its brushed chapter ring, precise 120-click bezel, clear sapphire crystal, excellent case finishing, and significantly improved lume. The watch is considered a terrific value with solid construction. Some owners express a preference for a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. On balance, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its tool-like features and excellent value.

From video reviewers
