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.

Longines FLAGSHIP HERITAGE

The Longines Flagship Heritage is widely praised for its impeccable finishing, timeless vintage-inspired design, and exceptional value, with reviewers highlighting its elegant cream dial with gilt markers, dauphine hands, and applied logo, as well as its comfortable 38.5mm case size. Owners appreciate its refined aesthetic, suitable for dressed occasions and as a first watch, and some note the special design on the case back. However, its 42-hour power reserve and 12.4mm thickness are flagged as drawbacks, with one owner suspecting an issue with the self-winding mechanism. Overall, owners and reviewers rate the Longines Flagship Heritage highly for its elegant vintage design and exceptional value at its price point.
