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.

Ratio FreeDiver Professional Quartz

Owners widely praise the Ratio FreeDiver Professional Sapphire Black Dial Quartz RTF005 200M Men's Watch for its exceptional value, with many highlighting its comfortable bracelet, low profile, and thin 10mm case. The watch features a sapphire crystal, all-stainless steel construction, and a screw-down crown, with reviewers noting its excellent C3 lume and precise bezel action that aligns perfectly with minimal back play. Some owners find the bracelet clasp feels cheap and suggest improvements for sapphire legibility, though the overall construction is considered solid. Overall, owners rate the Ratio FreeDiver Professional Sapphire Black Dial Quartz RTF005 200M Men's Watch highly for its robust build and comfortable wearability at its price point.
