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.

Scurfa Diver One ND513 Black 300m

Owners widely praise the Scurfa Diver One ND513 Black 300m as an excellent tool watch, valuing its toughness, legibility, and 300m water resistance. Reviewers and owners alike highlight the robust 40mm case and precise 120-click bezel, with one owner appreciating its versatility as an everyday and business-casual watch. The watch features tritium lume, a domed sapphire crystal with blue AR coating, and a matte black dial. Some owners note the lume is not as impressive as on the brand's higher-end models. Overall, owners rate the Scurfa Diver One ND513 Black 300m highly for its robust build and tool-watch functionality at its price point.
