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 SST GMT

Owners praise the Glycine Airman SST GMT for its comfortable wear, good build quality, accuracy, lume, and historical significance. The 24-hour dial and compressor-style GMT ring are noted as great features. One owner found the Sellita SW330 movement authentic, though expected Glycine branding on the rotor. The dial is considered busy, and one owner experienced the watch stopping after a day on a winder with a rattling rotor, suggesting service. On balance, owners rate the Glycine Airman SST GMT highly for its comfortable wear and historical significance.

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.
