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.

LONGINES SPIRIT FLYBACK PROTOTYPE

Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing, COSC-certified movement, and value as a flyback chronograph. Reviewers highlight its refined 39.5mm case and simplified dial, while some owners appreciate the reduced thickness and improved wearability compared to larger variants, with a lug-to-lug distance noted as potentially long for smaller wrists. The watch features a 68-hour power reserve and a bespoke L791.4 movement. However, the case thickness is a consistent point of discussion, with multiple sources citing 17mm, though some reviewers suggest thoughtful design makes it wear closer to 13.5-14mm. Owners are split on the dial's aesthetic, with some preferring previous configurations with gold subdial rings and concentric textures over the current flat matte dial and cut-off numbers. The leather strap is also noted as stiff and pinching.
