What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport GMT

Owners widely praise the Glycine Combat Sub Sport GMT for its refined feel and sleek wearability, with many noting its thin profile and downward-curving lugs contribute to comfort. Reviewers and owners alike highlight its exceptional value and solid build quality. Some owners report the lume is sub-par, and one noted a slightly off-color lume pip on the chapter ring. Accuracy figures vary, with one owner achieving +1 second per day after regulation, while another found the stock beat error acceptable for the price. The power reserve can be inconsistent, and the lack of a date cyclops is a minor drawback for some. On balance, owners rate the Glycine Combat Sub Sport GMT highly for its impressive thinness and refined aesthetic 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.
