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 39.5 mm

The Formex Reef 39.5 mm is widely praised for its refined finishing, comfortable and well-proportioned case design, and impressive specifications for its price point, including COSC-certified Sellita SW300-1 movement and 300m water resistance. Owners and reviewers highlight the tool-less micro-adjust clasp and quick-release spring bars as practical features. Some reviewers note that the 22mm lug width feels slightly disproportionate to the smaller case, and the bracelet could benefit from more taper, though this is a point of contention for some owners who value the overall package. A prototype crown protrusion issue is noted as being addressed for production. On balance, owners and reviewers rate the Formex Reef 39.5 mm highly for its excellent value and well-executed design.

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.
