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 Goofy Panda (Gen3)

Owners widely praise the Studio Underd0g Goofy Panda (Gen3) for its fun, playful personality and attractive, well-executed textured degradé dial, finding it a cool and versatile watch for daily wear at a fair price point. The 38.5mm case size and sapphire crystal are noted as positives, with some finding it looks better in person than in photos. However, some owners consider the Studio Underd0g Goofy Panda (Gen3) overpriced for its Seagull ST-1901 movement, with a few expressing concerns about movement reliability, with one reporting their watch stopped after only a few hours. On balance, owners and reviewers find the Studio Underd0g Goofy Panda (Gen3) a joy to own due to its unique design and dial execution at its price.
