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.
