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

Oak & Oscar The Humboldt GMT owners widely praise its exceptional accuracy, often running at or near 0 seconds per day, and its comfortable wearability with subtle design details. The construction quality for the price point, sandwich lume, and anti-magnetic properties are also highlighted. Some owners find the bracelet sizing adjustment slightly awkward, and one noted the lume could be brighter. Overall, owners rate the Oak & Oscar The Humboldt GMT highly for its accuracy and comfortable wearability.
