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.

Sunrex 321

The compact 37mm case size is a strength. The watch offers versatility with included FKM rubber and leather straps.
