The DOXA SUB 300 Beta is praised for its refined aesthetic and vintage charm, with a wave-patterned dial, ceramic bezel, and box-domed sapphire crystal. Owners find its 42.5mm case wears well due to its compact feel and short lug-to-lug length, making it suitable for smaller wrists and comfortable for all-day wear. The watch is powered by an automatic movement with a 38-hour power reserve. Some reviewers question the inclusion of a helium escape valve on this less tool-oriented design, and one owner notes the polished bezel is prone to scratches. Overall, owners and reviewers appreciate the DOXA SUB 300 Beta for its blend of classic dive watch appeal and modern wearability.
