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.

Yema Superman Titanium Tourbillon CMM.31 Limited Edition

The Yema Superman Titanium Tourbillon CMM.31 Limited Edition is noted for its in-house titanium tourbillon movement offering a 105-hour power reserve and 200m water resistance, alongside a unique asphalt-grained dial. Owners find the 43mm size wearable, with one describing it as a contradictory "toolwatch" with exceptional movement craftsmanship. A reviewer flags the bracelet clasp's extension system as crude. On balance, owners and reviewers highlight the impressive movement and dial as key strengths of the Yema Superman Titanium Tourbillon CMM.31 Limited Edition.
