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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
