What people say

Owners + reviewers, side by side

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 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.

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.
