What people say

Owners + reviewers, side by side

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

Nivada Grenchen Chronomaster Valjoux

The Nivada Grenchen Chronomaster is praised for its vintage aesthetic and versatility, with the Aventurine Blue variant offering a unique starry dial and world time bezel. Owners note the sub-dials are small and difficult to read, and the Sellita SW510 movement exhibits rotor wobble and hand play. The $5,000 price point is a significant increase from previous reissues. Overall, owners rate the Nivada Grenchen Chronomaster highly for its vintage aesthetic and unique dial options, despite some concerns about sub-dial legibility and movement characteristics.

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.
