Reviews

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

Filippo Loreti Watches Eterno Automatic Blue Diver

Owners widely report significant shipping delays and poor quality control, with some experiencing watches stopping working within a year and customer service offering no resolution. The brand is frequently described as a fashion or "drop shipper" brand rather than a serious watchmaker, with criticisms leveled at aggressive marketing and claims of Italian design when movements are Japanese. Some owners find the watches beautiful and appreciate features like sapphire crystal, while others consider them overpriced and not worth more than $40-$50. On balance, owners and community members express significant concerns regarding value and reliability, leading many to advise avoiding the brand.

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.
