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 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.

RZE Urbanist

The RZE Urbanist is widely praised as a fantastic, lightweight, "grab and go" everyday watch. Owners highlight its durable titanium case with scratch-resistant coatings and sapphire crystal. The solar movement is noted for keeping good time and is guaranteed for life. Production models feature a push-in crown, a change from earlier screw-down versions. Overall, owners rate the RZE Urbanist highly for its durable, lightweight titanium construction and reliable solar movement.

From video reviewers

The RZE Urbanist features a Japanese movement for accurate timekeeping and reliable performance. The watch's lume brightness is a shared weakness, with both reviewers noting it could be improved. Reviewers disagree on the watch's value, with one reviewer considering it a 'great value' for the price, while the other highlights its solar power feature as a significant strength.
