What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Promaster Diver

The Citizen Promaster Diver is praised for its handsome dial made from recycled materials and lightweight comfort, with one owner noting its Ecodrive movement achieved +1 second in 7 days. Another owner highlights the "Kermit" NY0071–81E's Super Titanium case and Japanese 8203 calibre movement, which has an accuracy of +20/-40 seconds per day. Criticisms include potential difficulty maintaining charge in a large collection and a slightly misaligned bezel and chapter ring, with a preference for sapphire crystal and ceramic bezel over mineral glass and aluminum. One owner found their 1990 Promaster Aqualand's quartz movement required repairs twice. Overall, owners value the Citizen Promaster Diver for its unique dial and comfortable wear, though movement accuracy and material choices are points of varied observation.

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.
