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.

Horage Supersede Dual Time

The Horage Supersede Dual Time is widely praised for its technically impressive, 98% in-house micro-rotor GMT movement, thin 10mm case, and 39.5mm size, along with excellent finishing and a comfortable bracelet. Owners also note its robust 200m water resistance and 904L steel construction. Some reviewers find the GMT sub-dial illegible, and one owner reported a bezel alignment issue requiring repair, while another flagged the date setting as potentially confusing. The $8,000 price point is considered high by some, though others view it as exceptional value for the movement and build quality. On balance, owners and reviewers rate the Horage Supersede Dual Time highly for its innovative micro-rotor GMT movement and high level of finishing at its price point.
