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.

Sternglas Marus

The Sternglas Marus is widely praised for its well-built, heavy feel and excellent bezel action, considered the best in its price range. Despite its 42mm diameter and 52mm lug-to-lug, owners report it fits surprisingly well on slim wrists. A reviewer notes the short seconds hand as a drawback, but highlights the watch as a fun, affordable starting point for a collection, featuring a vibrant Pepsi bezel and an anthracite dial that shifts in appearance, powered by a Miyota 8215 movement for €399. Overall, owners and reviewers rate the Sternglas Marus highly for its robust build and superior bezel at its price point.
