What people say

Owners + reviewers, side by side

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

Lorier Hyperion SII Skyward

Owners widely praise the Lorier Hyperion SII Skyward for its comfortable, thin, and light wearability, with one owner noting a perfect case width and another highlighting its 10.7mm thickness. The bi-directional GMT bezel is described as decent for its price, and the movement is considered fine and accurate, making it a low-key travel watch. The bracelet is also noted as well-made and finished for the price. On balance, owners rate the Lorier Hyperion SII Skyward highly for its comfortable wearability and value as a mechanical GMT.

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.
