What people say

Owners + reviewers, side by side

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

LONGINES AVIGATION BIGEYE

Owners and reviewers widely praise the Longines Avigation Bigeye for its unique, asymmetric dial, vintage military aesthetic, and cohesive design, with one reviewer noting its GPHG Best Revival prize win. The tactile chronograph pusher action and reliable L688.2 column wheel movement are highlighted, as is the watch's legibility and versatile strap-swapping potential due to its 20mm lug width. However, criticisms include the 30-minute sub-dial's three-minute hash marks, which some find compromise reading speed, and the lack of drilled lugs. The watch's thickness, around 14.45mm, is noted as typical for its movement, and some owners mention minor QC issues with chronograph hand alignment and a loud rotor. On balance, owners and reviewers rate the Longines Avigation Bigeye highly for its distinctive vintage-inspired design and solid chronograph performance 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.
