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 Burnt Pepperoni (Gen3)

Owners are split on the Studio Underd0g Burnt Pepperoni (Gen3)'s aesthetic, with some finding it an unnecessary novelty and others loving its unique look. It is powered by the manually-wound Seagull ST-1901B chronograph movement, regulated in-house to -10/+15 seconds per day, and features a 38.5mm black PVD-coated stainless steel case with a dégradé dial and crackle-black hands with burnt-orange lume. Some consider its price steep, particularly for a watch with a manual-wind movement. On balance, the Studio Underd0g Burnt Pepperoni (Gen3) elicits a polarized reaction due to its distinctive design, with opinions divided on its visual appeal and value proposition.
