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.

YEMA x Silberstein Marine 2 CMM.20 Limited Edition

The YEMA x Silberstein Marine 2 CMM.20 Limited Edition is noted for its slim 39mm case and in-house CMM.20 micro-rotor movement, offering 300 meters of water resistance and a 70-hour power reserve. Reviewers highlight the watch's thin profile and flowing case design, as well as its black lacquered enamel dial. However, the bezel's lack of numbers is considered a practical drawback, and one reviewer noted the audible spin of the micro-rotor, which was unexpected given the €1,990 price for the 200-piece limited edition. The included leather strap is also seen as less suited for the watch's dive capabilities. Overall, reviewers appreciate the YEMA x Silberstein Marine 2 CMM.20 Limited Edition for its slim design and in-house movement, though practical considerations regarding the bezel and strap are noted.
