What people say

Owners + reviewers, side by side

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

Horage Autark Tourbillon GMT

Owners widely praise the Horage Autark Tourbillon GMT for its Swiss-made tourbillon, platinum micro-rotor, and super-thin 9mm titanium case design, noting little less than premium feel in case and movement finishing. The dial features a sub-seconds, date, and power reserve indicator, powered by an in-house movement with a 60-hour reserve. Some find the sub-dial illegible and hour hands difficult to read quickly, while others note the stepped bezel is not to their taste and the micro-rotor can be loud. The bracelet's lack of taper is also flagged as a drawback. On balance, owners rate the Horage Autark Tourbillon GMT highly for its premium finishing and innovative technical features at its price point.

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.
