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.

Orient Multi-Year Calendar

Owners report the Orient Multi-Year Calendar features a complex analog display for tracking days and dates across multiple years, housed in a 45mm stainless steel case with 100m water resistance. Some owners view the watch as a visually appealing novelty, noting that manual adjustment is required for months and that the older 20-year calendar version is difficult to find. One owner observed only light signs of wear on their watch, with minor desk rash on the buckle visible only under magnification. On balance, owners appreciate the unique calendar complication as a visually appealing novelty.
