What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Glycine Combat Sub Sport GMT Bronze

Owners report the Glycine Combat Sub Sport GMT Bronze offers a unique aesthetic and remarkable value, often found at significant discounts. One owner notes difficulty matching straps with the bronze dial and that seawater exposure can cause rapid, undesirable patina, suggesting regular cleaning mitigates issues. Another owner flags sub-par lume that is difficult to read at night and an inconsistent power reserve that may not reach the advertised 42 hours. On balance, owners value the Glycine Combat Sub Sport GMT Bronze for its unique aesthetic and strong value proposition, though lume and power reserve performance are noted concerns.

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.
