What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional thinness, with multiple sources noting profiles between 10.4mm and 11mm, comfortable wearability on a variety of wrist sizes due to its proportions and contoured lugs, and its value, especially when found under $400. Some owners highlight its refined finishing and unique, non-homage design, while others appreciate its ruggedness and durability, with one noting PVD coating remained flawless after three years of heavy use. Accuracy figures range from excellent, with one owner reporting only 2 seconds lost per day, to inconsistent power reserve and occasional reported issues with the movement and stem. The lume is described as subpar by some, though one owner found it marginally better than a Seiko SKX007. Reservations are occasionally raised regarding warranty service and the use of folded end links on the bracelet.

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.
