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.

Wolbrook Skindiver Automatic

Owners widely praise the Wolbrook Skindiver Automatic 38mm for its vintage-inspired design, compact 38mm size, and tool-like aesthetic, offering good value for its price. The watch features ridiculously bright and long-lasting lume, a clean dial, and a Miyota 9039 no-date movement. Some owners find the push-pull crown a drawback, while others note the clasp and some bracelet links can feel sharp. Opinions are split on the bracelet design, with some finding it confusing and others praising its articulation and micro-adjustments. One owner found the 40mm case felt larger than expected. Overall, owners rate the Wolbrook Skindiver Automatic 38mm highly for its vintage aesthetic and tool-watch appeal at a reasonable price.
