Reviews

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

Glycine Combat Sub

Owners widely praise the Glycine Combat Sub for its slim profile, with multiple sources noting thicknesses around 10.4mm to 10.8mm, and its well-proportioned, non-homage design that wears comfortably. Reviewers and owners consistently highlight its exceptional value and quality for the price, with one owner reporting accuracy rivaling COSC standards and exceptional durability. The bezel action is described as buttery smooth, and the dial features tasteful indices and crisp fonts, with one specific gold and blue variant lauded for its refined aesthetic. However, multiple sources flag the lume as sub-par and difficult to read at night, and some owners note inconsistent power reserve. Overall, owners and reviewers rate the Glycine Combat Sub highly for its exceptional value and slim, comfortable wearability.

From video reviewers

The slim case profile and comfortable wearability are praised. The bezel action received criticism for having slight play and a less-than-satisfying click.

Lum-Tec Solar Marine

Owners widely praise the Lum-Tec Solar Marine for its all-black diver design, excellent lume, and rugged, tank-like build. This 39mm watch is noted as a great smaller option, fitting a 7-inch wrist perfectly and suitable for extensive water activities. One owner cautions that the PVD coating may wear and chip within a year. On balance, owners rate the Lum-Tec Solar Marine highly for its rugged build and excellent lume in a compact dive watch package.
