What people say

Owners + reviewers, side by side

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

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.

Horage Supersede GMT

The Horage Supersede GMT is widely praised for its innovative micro-rotor movement and impressive finishing. Owners and reviewers highlight its value as a true GMT sports watch, noting the compact 39.5mm case and 200m water resistance. The K2 movement offers a 72-hour power reserve, and updates include an optional platinum rotor, a luminous seconds hand tip, and a new micro-adjustable clasp. One potential hesitation for buyers is the inability to see the watch in person. Overall, owners and reviewers rate the Horage Supersede GMT highly for its innovative micro-rotor movement and excellent value.

From video reviewers

The Horage Supersede GMT features a unique case design that blends different styles. A notable strength is its in-house K2 micro-rotor movement. One weakness is the relatively average lume brightness.
