Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
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.
Owners widely praise the Studio Underd0g Salmon for its unique, two-layered dial inspired by salmon skin, featuring a radially brushed metallic orange-pink lower part and a coarse, silvery dégradé shimmer upper part. The watch is powered by a decorated Swiss mono pusher movement with silky smooth winding, blued screws, and anthracite bridges, which one owner finds impressive. Accuracy is reported at ±5 seconds per day. Some owners find the £1700-£1800 price point difficult, especially given styling similarities to previous models. Overall, owners and reviewers rate the Studio Underd0g Salmon highly for its distinctive dial design and well-finished, smooth-winding monopusher movement.
