What people say

Owners + reviewers, side by side

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

Sugess Tourbillon Master SU8001

Owners widely praise the Sugess Tourbillon Master for its accessible tourbillon complication and value, with one owner noting an initial accuracy of +2 seconds per day. However, community feedback flags a winding stem that feels flimsy and straps that are considered poor, featuring a comically large buckle. Some owners report a degradation in accuracy to around -20 seconds per day after a month, and the steel case edges are described as rounded with the material proving soft and prone to scratching. On balance, owners view the Sugess Tourbillon Master as a remarkable value for its tourbillon feature, despite concerns regarding strap quality and long-term material durability.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
