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.

Longines HYDROCONQUEST

Owners widely praise the Longines Hydroconquest for its attractive sunburst blue dial and accurate timekeeping, with one owner reporting a loss of only 2 seconds per day. However, the bracelet is frequently criticized for lacking micro-adjustments and having pinch-prone links, and the screw-down crown is noted as inconvenient and difficult to operate by multiple owners. Some owners also flag the bezel action as ratchety with back play, and one owner found the lugs sharp and the overall design uncomfortable, leading them to sell the watch. On balance, owners appreciate the Longines Hydroconquest's aesthetic appeal and value, despite significant reservations about its bracelet and crown usability.

From video reviewers

The bezel action is praised for its smooth and precise rotation. Lume brightness is a shared weakness, found to be somewhat lacking. Reviewers disagreed on the watch's value proposition compared to alternatives.
