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 GMT

Owners widely appreciate the Glycine Airman GMT's classic pilot design and consider it a well-built watch, with some noting the 39mm models offer perfect sizing and 200m water resistance. Reviewers praise the plexiglass crystal and matte dial, while some owners find the GMT hand visually similar to the minute hand, making it difficult to read. Accuracy from the Sellita-based movement is described as acceptable, though dial lume pips are noted as weaker than the hands. On balance, owners and reviewers value the Glycine Airman GMT for its faithful reproduction of a classic pilot watch design, despite some legibility concerns with the GMT hand.

Oak & Oscar The Humboldt GMT SAR Edition

Oak & Oscar The Humboldt GMT SAR Edition is praised for its anti-magnetic properties, sandwich lume dial, and overall construction quality for its price point. It features a brushed Grade 5 titanium case, a navy blue sandwich dial with an orange minute track and seconds hand, and a Sellita SW330 movement with a 56-hour power reserve. Minor drawbacks noted include bracelet sizing adjustment and lume brightness. On balance, owners and reviewers rate Oak & Oscar The Humboldt GMT SAR Edition highly for its robust construction and unique dial design at its price point.
