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 Smoked Salmon

Owners widely praise the Studio Underd0g Smoked Salmon's clean, elegant design and unique appeal, with some appreciating its simple, unbranded look and others noting its conversation-starting ability. The watch features a two-layered, metallic salmon-skin-inspired dial housed in a 38.5mm stainless steel case. It is powered by a Swiss-made Sellita SW510 M MP b monopusher chronograph movement, with advertised accuracy of ±5 seconds per day. Some owners find the £1700/€1,800 price point high, and one owner noted a "raised glass fishbowl over the dial." Overall, owners rate the Studio Underd0g Smoked Salmon highly for its unique dial design and conversation-starting appeal.
