Reviews

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

CWC RN Quartz Divers Watch Mk.2 Day/Date, Matte Top

Owners and reviewers widely praise the CWC (Cabot Watch Company) RN Quartz Divers Watch Mk.2 Day/Date, Matte Top for its legible, classic dial design, excellent lume that lasts all night, and comfortable 41mm case size. The 120-click bezel is described as having a solid feel and being "perfection," with the quartz seconds hand hitting markers precisely. Sources note the matte top case with polished sides and the sapphire crystal as significant upgrades. Some reviewers question its value proposition, with one owner noting the "vintage tinted" paint on the dial markers and hands appears slightly too gold and glossy, and another mentioning the case is polished on all surfaces. Overall, owners and reviewers rate the CWC (Cabot Watch Company) RN Quartz Divers Watch Mk.2 Day/Date, Matte Top highly for its durable construction and classic military dive aesthetic.

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.
