What people say

Owners + reviewers, side by side

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

Glycine Airman No. 1 GMT

Owners widely praise the Glycine Airman No. 1 GMT for its historical significance and attractive dial. However, some find the 36mm case size to be a bit small, and the GMT hand can be difficult to distinguish from the minute hand. The watch has a very limited 3ATM water resistance. Later versions feature sapphire crystals, differing from earlier plexi models. Overall, owners value the Glycine Airman No. 1 GMT for its historical appeal and dial design, despite minor legibility and sizing concerns.

From video reviewers

The case finishing and dial colors are praised. The value proposition is tied to a sale price, with questions about long-term competitiveness.

Nivada Grenchen Super Antarctic 35mm Automatic

The Nivada Grenchen Super Antarctic 35mm Automatic is praised as a fantastic time-only release with excellent legibility due to its large indices and hands, and a comfortable 38mm case. Reviewers highlight its vintage-accurate 10.1mm thinness and 200m water resistance. An owner reports accuracy gains of +6 to +9 seconds per day, and one reviewer notes the "cream" lume color appears too yellow for faux patina. Overall, owners and reviewers rate the Nivada Grenchen Super Antarctic 35mm Automatic highly for its comfortable size and excellent legibility at its price point.
