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 Navygraf Chrono

Owners praise the Yema Navygraf Chrono for its handsome, versatile design and the value offered by its Valjoux 7750 movement. A reviewer notes the 40mm case's fully polished finish, which some feel clashes with its sporty aesthetic, and mentions its 13.9mm thickness is noticeable. One owner reported wearing the Yema Navygraf Chrono for two months without issues, receiving compliments. On balance, owners and reviewers find the Yema Navygraf Chrono to be a good-looking and well-specced watch for its price.
