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.

Grand Seiko SLGH017

Grand Seiko SLGH017 owners and reviewers widely praise its impeccable finishing on the applied markers and handset, and its lightweight titanium case and bracelet. The high-beat 9SA5 movement is noted for its approximately 80-hour power reserve, with accuracy figures reported by owners ranging from +4 sec/day to +5 to -3 seconds per day, though some owners express concerns about accuracy deviating significantly from specifications. Some find the "Night Birch" dial stunning and appreciate the Evo 9 case design, while others note the dial texture appears less pronounced on its matte black surface and criticize the handset's proportions and lack of lume. The Grand Seiko SLGH017 is priced at €10,500. On balance, owners and reviewers rate the Grand Seiko SLGH017 highly for its lightweight titanium construction and impeccable finishing.
