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.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
