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 The Mimosa

Studio Underd0g The Mimosa is praised for its playful, layered dial design evoking a cocktail, its comfortable 38mm cushion case, and the tactile experience of its manual-wind Sellita SW210-1 movement. Reviewers appreciate the fun collaboration and the easter egg of the textured dial, finding it fitting for the watch's playful nature, and one owner notes its 10atm water resistance rating was proven by surviving a swim. Owners and reviewers consider its $1,300 price steep for the Sellita SW210-1 movement, with some wishing for more competitive pricing or questioning if it offers the best value. Overall, owners and reviewers rate Studio Underd0g The Mimosa highly for its unique, playful dial design and comfortable wearability.
