What people say

Owners + reviewers, side by side

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

CWC 1980 RN Divers Automatic Re-Issue Watch

The CWC 1980 RN Divers Automatic Re-Issue Watch is widely praised for its faithful recreation of vintage details, including its dial layout with markers touching the chapter ring and pointed crown guards. Owners and reviewers note its reasonable size and the original minute hand design. However, the lume is a point of contention: some find the "faux patina" tint too gold and glossy, while others specifically criticize the mismatched lume color between hands and hour markers, with the hour marker lume described as overly shiny and convex. On balance, the CWC 1980 RN Divers Automatic Re-Issue Watch is highly regarded for its authentic vintage aesthetic and wearability, despite mixed opinions on the lume application.

From video reviewers

The watch's accurate movement is a notable strength. A potential weakness is its relatively high price point. Reviewers disagree on the watch's water-resistance, with one reviewer suggesting it could be improved and the other not mentioning any issues with water-resistance.

Yema Wristmaster Slim CMM.20

The Yema Wristmaster Slim CMM.20 is widely praised for its compelling integrated bracelet design and comfortable 39mm wearability. Reviewers highlight its impressive value, featuring an in-house CMM.20 micro-rotor movement with a 70-hour power reserve, adjusted to -3/+7 seconds per day, all within a slim 9mm case. Some note the domed sapphire crystal can produce glare and the dial text is quite small. On balance, reviewers rate the Yema Wristmaster Slim CMM.20 highly for its integrated design and value proposition with a micro-rotor movement.
