What people say

Owners + reviewers, side by side

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

Lorier Hydra SIII

Owners and reviewers praise the Lorier Hydra SIII for its value, GMT functionality via the Miyota 9075 movement, and classic travel-diver aesthetics. Some reviewers note the finishing is simple or a tad rough around the edges, while others find it good for the price. Accuracy figures range from +7 to +8.5 seconds per day. The domed Hesalite crystal may exhibit distortion. Overall, owners and reviewers rate the Lorier Hydra SIII highly for its feature set and value proposition in a travel-diver format.

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.
