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.

Baltic Hermétique Summer

Reviewers highlight the Baltic Hermétique Summer's compact 37mm brushed case with a polished bezel and 150 meters of water resistance. The watch features glossy dials in bright colors with raised BGW9 Super-LumiNova indices that emit a strong blue glow, and it comes with color-matched FKM rubber straps or Baltic bracelets. The Miyota 9039 movement supports hacking and hand-winding. However, the recessed crown can be difficult to manipulate if fingernails are not long enough, and the movement has a stated accuracy of -10/+30 seconds per day. Overall, reviewers praise the Baltic Hermétique Summer for its well-balanced, colorful dials and strong lume at an affordable price point.
