What people say

Owners + reviewers, side by side

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

Gruppo Gamma Field III

The watch's 200m water resistance is a notable strength. A weakness is the use of the Seiko NH34A GMT movement, which might be considered less desirable than some other options due to its relatively lower grade compared to other movements in this price range.

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.
