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.

Traska Summiteer Charcoal

Owners widely praise the Traska Summiteer Charcoal for its comfortable 38.5mm size, short lugs, clean dial, and proud crystal, with some noting its excellent fit and finish and smooth winding action. Timekeeping averages +2 seconds per day, and the hardened steel treatment is a valued addition. Some owners find the dial plain and prefer textured alternatives, and one owner experienced dial alignment issues with a recent Traska release. The bracelet is criticized by some for being noisy, sagging, and having a clasp with rough edges, though others praise its on-the-fly micro-adjustment. On balance, owners rate the Traska Summiteer Charcoal highly for its overall package and value proposition at its price point.
