CWC RN Automatic Divers Watch Mk.2

The CWC RN Automatic Divers Watch Mk.2 is praised for its build quality, utilitarian capabilities, and classic design, with owners appreciating its historical connection to the UK Navy and its suitability as a tool watch. Some find the fixed spring bars a drawback, limiting strap choices. One owner noted average finishing and a chipped polish. The CWC RN Automatic Divers Watch Mk.2 is a 41mm automatic diver with 300m water resistance. On balance, owners view the CWC RN Automatic Divers Watch Mk.2 positively for its heritage and robust tool-watch nature, despite some reservations about its price and finishing.

Glycine Combat Sub Box Ceramic

Owners widely praise the Glycine Combat Sub Box Ceramic for its exceptional thinness, comfortable 41mm case, and unique, non-homage design, with one owner calling it the best dive watch under $400 due to superior finishing and value. The bezel action is described as solid and precise, and the dial is legible with good lume on the hands. However, multiple sources flag inconsistent power reserve, sub-par lume on the markers that fades quickly, and a subpar stock strap or bracelet. One owner reported the bezel detaching after a light bump, raising questions about build quality, while others note potential issues with the stem or anti-reflective coating. Accuracy figures vary, with one owner seeing it run about 2.5 seconds fast per day. Overall, owners rate the Glycine Combat Sub Box Ceramic highly for its comfortable thin case and unique design at its price point.
