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 GMT

Owners widely praise the Horage Autark Tourbillon GMT for its Swiss-made tourbillon, platinum micro-rotor, and super-thin 9mm titanium case design, noting little less than premium feel in case and movement finishing. The dial features a sub-seconds, date, and power reserve indicator, powered by an in-house movement with a 60-hour reserve. Some find the sub-dial illegible and hour hands difficult to read quickly, while others note the stepped bezel is not to their taste and the micro-rotor can be loud. The bracelet's lack of taper is also flagged as a drawback. On balance, owners rate the Horage Autark Tourbillon GMT highly for its premium finishing and innovative technical features at 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.
