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.

Monta Atlas

The Monta Atlas is widely praised for its exceptional wearability, with its comfortable 38.5mm case size and buttery bracelet frequently highlighted. Owners and reviewers alike commend its fit and finish, noting a mix of brushed, polished, and blasted surfaces. However, the rehaut on the opaline silver dial is considered nearly illegible for the 24-hour GMT scale, leading some to suggest other dial colors are more practical for GMT functionality. One owner also flagged the crown as less sturdy than anticipated and noted the AR coating attracts fingerprints. Overall, owners and reviewers rate the Monta Atlas highly for its comfortable dimensions and appealing finishing.

From video reviewers

The Monta Opalin Silver's dial is a notable strength, particularly its subtle gradient effect that adds depth to the watch without being too flashy. The watch offers a notable value proposition due to its movement, typically found in more expensive timepieces. The bracelet can be prone to rattle, which might be a trade-off for some buyers.
