What people say

Owners + reviewers, side by side

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

Maen Manhattan 37 seconde/seconde/

The Maen Manhattan 37 seconde/seconde/ is widely praised for its dressy styling and perceived step up in quality from other microbrands in its price bracket. Reviewers highlight its slim 9.3mm case, 100m water resistance, and comfortable integrated bracelet as key strengths, with the dark blue dial and hand-painted NYC references described as a hauntingly cool and versatile feature. The Sellita SW200-1 movement powers the time-only display, and the $1,499 price is considered good value. On balance, owners and reviewers rate the Maen Manhattan 37 seconde/seconde/ highly for its unique dial and slim, versatile design 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.
