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 Tangente 38 midnight blue

NOMOS Glashütte Tangente is widely praised for its simple Bauhaus design, thin and light wearability, and German in-house manual-winding Alpha movement. Owners note the galvanized white silver-plated dial and tempered blue steel hands contribute to its appeal. The 37.5mm case is reported to wear larger than its dimensions, while some find the 35mm size perfect, others feel it lacks immediate appeal and appears "puny" compared to larger watches, though its details are appreciated up close. Overall, owners rate the NOMOS Glashütte Tangente highly for its understated Bauhaus design and comfortable wearability.
