What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

DOXA SUB 750T

The DOXA SUB 750T is widely praised for its significantly slimmer 11.95mm thickness on a 45mm case, which reviewers and owners agree makes the barrel-shaped dive watch surprisingly wearable and comfortable. Its Sellita SW300 movement provides a 56-hour power reserve, and the watch retains a 750-meter water resistance rating. Some owners find the watch expensive and its dial cluttered, while others appreciate its unique design and inner bezel markings. The integrated beads-of-rice bracelet receives mixed feedback, with some finding it comfortable and others desiring more tapering. Overall, owners and reviewers rate the DOXA SUB 750T highly for its improved wearability due to its slim profile at a substantial 45mm size.

From video reviewers

The DOXA SUB 750T's slimmed-down 11.95mm case thickness is a significant strength cited by multiple reviewers. Reviewers did not reach a consensus on any weaknesses.

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.
