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 S446 GMT

Owners widely praise the Sugess Seestern S446 GMT for its outstanding finishing and materials at its price point, with specific mentions of the cream or ivory dial, polished hands, and clear crystal offering superb legibility. Accuracy is generally good, with one owner reporting +2/3 seconds per day from the Seiko NH34A movement. Some owners find the lume is not a strong point, and the bracelet clasp could benefit from more micro-adjustment, with screw pins noted as cheap. The GMT hand is described as flat by some, and opinions are split on the "Sugess" versus "Seestern" logo. Overall, owners rate the Sugess Seestern S446 GMT highly for its beautiful dial and excellent build quality for the price.

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.
