What people say

Owners + reviewers, side by side

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

CWC 6BB-WR

The CWC 6BB-WR is widely praised for its legible matte black dial, strong lume, and crisp chronograph operation. Owners and reviewers note its military heritage and rugged, confidence-inspiring build with a screw-down crown and pushers. The Sellita SW510 BH b automatic movement kept time within COSC range in testing. However, its 14.9mm thickness and 80g weight make it wear large, and the cam-lever movement lacks the satisfying click of a column wheel. Fixed bars limit strap options. On balance, owners and reviewers rate the CWC 6BB-WR highly for its legible dial and robust pilot chronograph design at its price point.

Yema Navygraf Pearl CMM.20

The Yema Navygraf Pearl CMM.20 is praised for its elegant and slim case design, measuring between 9.5mm and 9.75mm thick, and its unique mother-of-pearl dial and bezel. The watch features functional dive watch elements like 200-meter water resistance and is powered by the in-house CMM.20 micro-rotor movement, which offers a 70-hour power reserve and is adjusted to -3/+7 seconds a day. Overall, reviewers highlight the Yema Navygraf Pearl CMM.20's sophisticated aesthetic and slim profile as its primary strengths.
