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.

Tissot Seastar 1000 Quartz Chronograph

The Tissot Seastar 1000 Quartz Chronograph is widely praised for its excellent value, solid build, and 300m water resistance, making it a capable summer watch. Owners appreciate its comfortable size, with one noting the 40mm variant as a "just right" fit, and others highlighting the attractive mineral bezels and throwback aesthetics of certain colorways. The watch features adequate lume on the dial and hands, with a green lume pip on the bezel, and a screw-down crown with decent grip. However, some criticisms have been raised. Reviewers and owners note a non-reflective crystal that can cause glare, mediocre lume in general, and excessive polishing on the case. The bracelet and clasp are frequently described as rattly and flimsy, with one owner finding the 19mm lug width too thin. There are also comments about a busy dial, ill-proportioned hands and indices, and a bezel that can be hard to read in certain light.
