What people say

Owners + reviewers, side by side

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

Spinnaker Tesei Mille Metri GMT

The Spinnaker Fleuss Midnight Black features a reliable and accurate Japanese TMI NH35 Automatic Movement with 3 Hands and Date. A potential drawback is the watch's relatively low 15 ATM water-resistance rating compared to other watches in its class. Reviewers disagree on the watch's suitability for larger wrists, with one reviewer noting a 43mm diameter and 51mm lug-to-lug fit, while the other mentions a 51mm lug-to-lug measurement.

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.
