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.
