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 The Manhattan

Studio Underd0g The Manhattan is widely praised for its captivating amber fumé sunray dial with a raised sapphire disc, creating unique depth and animation. Owners appreciate the comfortable 38mm cushion case and the tactile winding feel of the manual-wind Sellita SW210-1 movement. Some in the community note the dial's design elements are reminiscent of Fears. The watch offers 10atm water resistance. Overall, owners and reviewers rate Studio Underd0g The Manhattan highly for its distinctive dial and comfortable wearability.
