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 SU8230

Owners widely praise the Sugess Tourbillon Master for its stunning enamel dial and impressive finishing at its price point. Accuracy figures vary, with one owner reporting -12s/day and another +6 to +11s/day. Caveats include a cumbersome winding crown, limited 50m water resistance, a 21mm lug width, and a non-hacking movement, with one owner noting a power reserve around two days and noticeable resistance when winding. On balance, owners rate the Sugess Tourbillon Master highly for its visually striking dial and finishing, which significantly elevates its perceived value.

Yema Granvelle CMM.29

Owners praise the Yema Granvelle CMM.29's gorgeous dial, noting its guilloché pattern and carved hour indices that catch the light. One owner describes the movement as a "feast for the eyes" but finds the watch frustrating at work due to its lack of a specific function. On balance, owners appreciate the Yema Granvelle CMM.29 for its visually striking dial and movement finishing, with some finding its utility limited in certain professional contexts.
