What people say

Owners + reviewers, side by side

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

Horage Autark Tourbillon

The Horage Autark Tourbillon is noted for its technical achievement as an accessible Swiss-made micro-rotor tourbillon, featuring an in-house calibre with a ceramic ball bearing design and silicon components. It offers a 72-hour power reserve and 100m water resistance within a lightweight Grade 5 titanium 39.5mm case. Reviewers mention that some cosmetic aspects, like the power reserve indicator and dial color, were still being finalized on prototypes. Overall, reviewers highlight the Horage Autark Tourbillon as an audacious and accessible technical accomplishment for its price point.

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.
