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.

Formex Reef GMT

The Formex Reef GMT is widely praised for its unique porthole case shape, COSC-certified Sellita SW330-2 movement with good finishing, and comfortable quick-release bracelet with on-the-fly micro-adjustment. Reviewers note its robust construction, impressive specifications, and strong value proposition, with a slim 11.4mm profile accommodating 300m water resistance and an exhibition caseback. However, owners widely report the 53mm lug-to-lug span with male endlinks makes it too large for smaller wrists. Some find the bezel action stiff and potentially slippery, and a reviewer desired sharper finishing and edges, deeming the aesthetic too modernist. The GMT variant sacrifices a timing bezel unless swapped, and one owner notes sharp edges on the crown and crown guard. Overall, owners and reviewers highly rate the Formex Reef GMT for its exceptional value and well-executed features, particularly its bracelet system and COSC-certified movement.

From video reviewers

The watch features a COSC-certified SW330-2 GMT movement, which is visible through a sapphire crystal display case back and beautifully decorated. The watch's water-resistance of up to 300m/1000ft is a notable feature. The 42mm diameter may be too large for smaller wrists.
