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

Owners widely praise the Maen Manhattan 37's visually rich dial and refined finishing, with some noting its sleek, trim 37mm case and impressive timekeeping. The bracelet receives mixed reactions, with some finding it cheap and lacking compared to alternatives, while others appreciate its taper and overall value. One reviewer highlights the Ultra-Thin variant's slim 7.1mm case and 100m water resistance, powered by a manually wound ETA Pesaux 7001 movement. Conversely, another owner reports a Ronda 150 movement running fast at +18s/d to +24s/d, and some with 6.5-inch wrists find the 47mm lug-to-lug distance wears larger than expected. The Maen Manhattan 37 offers excellent value with its Art Deco-inspired design and remarkable light play on the dial. Overall, owners and reviewers rate the Maen Manhattan 37 highly for its visually rich dial and refined finishing at the price.

Formex Reef 39.5 mm

The Formex Reef 39.5 mm is widely praised for its refined finishing, comfortable and well-proportioned case design, and impressive specifications for its price point, including COSC-certified Sellita SW300-1 movement and 300m water resistance. Owners and reviewers highlight the tool-less micro-adjust clasp and quick-release spring bars as practical features. Some reviewers note that the 22mm lug width feels slightly disproportionate to the smaller case, and the bracelet could benefit from more taper, though this is a point of contention for some owners who value the overall package. A prototype crown protrusion issue is noted as being addressed for production. On balance, owners and reviewers rate the Formex Reef 39.5 mm highly for its excellent value and well-executed design.
