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.

Maen Manhattan 40

Owners appreciate the Maen Manhattan 40's thin case and unique dial, with some finding its proportions too large for smaller wrists. One owner noted a snagging crown and difficult winding action. Accuracy figures vary, with one owner reporting +18s/d to +24s/d on the 37mm version, while another owner of the 40mm model did not specify accuracy. On balance, owners and reviewers find the Maen Manhattan 40 to be a good value, with its thinness and dial finishing being key strengths.
