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 Heritage S436-2 BB GMT

Owners widely praise the Sugess Seestern Heritage S436-2 BB GMT for its 39mm sizing, 12mm thinness, and light yet solid feel, with many appreciating its legibility due to the matte dial, clear crystal, and strong lume, though one owner flags the lume as a weak point. The case finishing is considered excellent, and the blue dial and satin finish are favorably compared to alternatives. Some owners report issues with a loose bezel, with others finding it improved after tuning, and one owner notes the seconds hand is too short. The bracelet clasp lacks sufficient micro-adjustment and screw pins are difficult to remove. On balance, owners rate the Sugess Seestern Heritage S436-2 BB GMT highly for its comfortable wearability and attractive finishing at the price.
