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.

DOXA SUB 300

The DOXA SUB 300 is widely praised for its wearability and vibrant color options, with reviewers noting its compelling charm and modern updates like improved lume and a meter-based bezel. Owners report the DOXA SUB 300 wears comfortably, with its cushion case and beads-of-rice bracelet contributing to a smaller perceived size. The COSC-certified ETA 2824-2 movement is noted for its accuracy, with one owner seeing it gain only +1 second in three days. However, some owners flag issues with the bracelet's end links sticking out and a sharp clasp edge, while one reviewer found the lume to be a disappointment. The polished bezel surface is also noted as prone to scratches. Overall, owners and reviewers rate the DOXA SUB 300 highly for its wearability and distinct design, despite some minor finishing concerns.
