What people say

Owners + reviewers, side by side

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

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.

Gruppo Gamma Field III GMT

Owners praise the Gruppo Gamma Field III GMT for its look and value, with specific mentions of its sandwich dial and comfortable OEM straps. One owner notes incredible quality for the price across their Gruppo Gamma watches. The watch features a 40mm brushed stainless steel case, box sapphire crystal, and a Seiko NH34A movement with a 41-hour power reserve and stated accuracy of -20~+40 s/day. Some find the lack of a date window a drawback for a GMT, and question its differentiation from other NH34-powered watches. On balance, owners and reviewers find the Gruppo Gamma Field III GMT to be a good value with quality construction for its price point.
