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.

Studio Underd0g Smoked Salmon

Owners widely praise the Studio Underd0g Smoked Salmon's clean, elegant design and unique appeal, with some appreciating its simple, unbranded look and others noting its conversation-starting ability. The watch features a two-layered, metallic salmon-skin-inspired dial housed in a 38.5mm stainless steel case. It is powered by a Swiss-made Sellita SW510 M MP b monopusher chronograph movement, with advertised accuracy of ±5 seconds per day. Some owners find the £1700/€1,800 price point high, and one owner noted a "raised glass fishbowl over the dial." Overall, owners rate the Studio Underd0g Smoked Salmon highly for its unique dial design and conversation-starting appeal.
