BERNY BERNY-Men Automatic Compressor-style Diver Watch V4-AM181MS owners widely praise its solid build, comfortable wear, and excellent lume, with one owner noting the second crown operates the inner bezel. The watch features a compressor-style design, 200m water resistance, and sapphire crystal front and back, and its AR coating is considered superior by one owner. The fit and finish are reported to be on par with higher-end pieces, and many find it a sharp, well-fitting watch that they intend to keep long-term. Overall, owners rate the BERNY BERNY-Men Automatic Compressor-style Diver Watch V4-AM181MS highly for its exceptional value and impressive build quality at its price point.
Owners widely praise the BERNY BERNY-Men Automatic Diver Watch-AM155M for its exceptional anti-reflective coating and outstanding lume, with one owner describing it as an "absolute lume monster" that surpasses higher-priced alternatives. The watch's design is seen by some as inspired by the Seiko Monster, while others consider it a clone of the Halios Holotype, and the prominent "BERNY" branding on the dial is a deterrent for some potential buyers. Accuracy varies, with one owner reporting +17 seconds per day, while others do not specify. The Miyota 8215 movement is a point of contention for some enthusiasts, who feel it is a significant drawback at the $300 price point, though it is considered acceptable at lower price points or if replaced with an NH-35A. Overall, owners rate the BERNY BERNY-Men Automatic Diver Watch-AM155M highly for its impressive lume and anti-reflective coating at its price, despite some reservations about the movement and branding.
