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 SLGH017

Grand Seiko SLGH017 owners and reviewers widely praise its impeccable finishing on the applied markers and handset, and its lightweight titanium case and bracelet. The high-beat 9SA5 movement is noted for its approximately 80-hour power reserve, with accuracy figures reported by owners ranging from +4 sec/day to +5 to -3 seconds per day, though some owners express concerns about accuracy deviating significantly from specifications. Some find the "Night Birch" dial stunning and appreciate the Evo 9 case design, while others note the dial texture appears less pronounced on its matte black surface and criticize the handset's proportions and lack of lume. The Grand Seiko SLGH017 is priced at €10,500. On balance, owners and reviewers rate the Grand Seiko SLGH017 highly for its lightweight titanium construction and impeccable finishing.

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.
