What people say

Owners + reviewers, side by side

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

Grand Seiko SBGM245

Owners widely appreciate the Grand Seiko SBGM245 for its blend of sport and luxury, with one enthusiast highlighting its superior workmanship over quartz movements. However, opinions on its size vary, as one owner found the SBGM245 too large, preferring the comfort of a different variant. Overall, owners value the Grand Seiko SBGM245 for its refined craftsmanship, though its wearability is a point of personal preference.

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.
