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.

Sugess Seestern S446 GMT

Owners widely praise the Sugess Seestern S446 GMT for its outstanding finishing and materials at its price point, with specific mentions of the cream or ivory dial, polished hands, and clear crystal offering superb legibility. Accuracy is generally good, with one owner reporting +2/3 seconds per day from the Seiko NH34A movement. Some owners find the lume is not a strong point, and the bracelet clasp could benefit from more micro-adjustment, with screw pins noted as cheap. The GMT hand is described as flat by some, and opinions are split on the "Sugess" versus "Seestern" logo. Overall, owners rate the Sugess Seestern S446 GMT highly for its beautiful dial and excellent build quality for the price.
