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 praise the Glycine Airman GMT for its value and classic design, with specific appreciation for its 39mm sizing, 200m water resistance, and beefy signed crowns. Reviewers highlight its faithful re-issue nature, retaining vintage features like the plexiglass crystal and locking friction bezel with a thumbscrew crown, while some owners note its subtle blue degrade dial and red-tipped GMT hand. Accuracy from its Sellita-based automatic movement is described as acceptable, though some owners find the dual 12-hour and 24-hour scales confusing and the slim GMT hand difficult to read. On balance, enthusiasts and reviewers rate the Glycine Airman GMT highly for its vintage charm and robust build at its price point.

Sugess Seestern S456 GMT

Owners widely praise the Sugess Seestern S456 GMT for its excellent case finishing, deep blue sunburst dial, and crisp indices, with one owner rating the overall fit and finish 9.5 out of 10. The watch is noted for its legibility, strong lume that lasts about 4 hours, and accurate timekeeping around -4 seconds per day, with easy GMT hand adjustment. Some owners report issues with a loose or friction-based unidirectional bezel, while others find theirs tight and prefer a bidirectional GMT bezel. The sapphire crystal is described as clear and flat by some, but others find it very reflective with AR coating that could be improved. Sizing is generally considered good at 39mm with a 46mm lug-to-lug and 12mm thickness, though one owner expresses concern about its 49mm lug-to-lug and 41mm bezel diameter. Overall, owners rate the Sugess Seestern S456 GMT highly for its impressive finishing and dial at its price point.
