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.

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Original for its tool-watch aesthetic, legibility, and robust construction, with many noting excellent lume that lasts all night and precise day/date changes at midnight. The brushed stainless steel case is well-finished, and the 38mm size is considered comfortable and well-weighted despite being smaller than modern watches. Accuracy figures range from +2 seconds/day to +8 seconds/day, and some owners compare Fortis quality favorably to Omega. However, some users find the MSRP too high compared to brands like Sinn and Damasko, and one owner reported internal parts dislodging from a limited edition model. Concerns have also been raised about stripped lug screws on B-42 models and potential parts shortages due to past bankruptcy protection filings. Overall, owners rate the Fortis Original highly for its durable construction and tool-watch functionality at a competitive price point.
