Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Bulova Black Dial EPDM Rubber Strap Series X 98B358 for its reliability and durability, noting its ability to withstand daily wear, accidental drops, and swimming. The quilted dial texture is a specific point of appreciation. However, owners are divided on the stock straps, with one owner expressing a strong dislike and considering strap replacement or a bracelet. The watch features a quartz NN50 movement, a 300m water resistance rating, and a 45mm case. Overall, owners rate the Bulova Black Dial EPDM Rubber Strap Series X 98B358 highly for its robust build and attractive dial, though strap preference varies.
Owners widely praise the CWC (Cabot Watch Company) Automatic Divers Watch Mk.2 Black with Date for its excellent case finishing, robust 120-click bezel action, and significantly improved lume compared to previous models. Reviewers and owners alike highlight its military provenance and value as a unique daily wear, with a scratch-resistant sapphire crystal and day-date complication adding to its appeal. Some owners note fixed spring bars as a potential drawback, and one reviewer found the "faux patina" lume on a similar model to be too gold and glossy. Accuracy figures vary, with one owner reporting it running 3 seconds fast per 24 hours, while another observed the minute hand lume fading faster than the rest of the dial. Overall, owners rate the CWC (Cabot Watch Company) Automatic Divers Watch Mk.2 Black with Date highly for its solid construction, military significance, and practical features at its price point.
