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 Diver

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.

From video reviewers

The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
