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.

NOMOS Glashütte Tangomat ruthenium

Owners widely praise the NOMOS Glashütte Tangomat ruthenium for its Glashütte watchmaking and Bauhaus design, with one owner noting accuracy at +2 seconds/day and a 43-hour power reserve. Some owners find the Tangomat thicker than other models, with case proportions that may not suit its sharp design, and one owner expressed a preference for newer movements over the older Epsilon automatic. Overall, owners value the NOMOS Glashütte Tangomat ruthenium for its precise timekeeping and design ethos.
