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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
