Reviews

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

DOXA SUB 300 Beta

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.

Squale Master

Owners widely praise the Squale Master's outstanding quality and value, with one owner considering it the best dive watch at its price point. Reviewers and owners alike highlight the vintage dial and orange minute hand for excellent legibility, and the high-quality mesh bracelet is also a noted strength. A reviewer points out the Sellita SW 200-1 elaboré movement has an accuracy of ±7 to ±20 seconds per day, and the 17mm thickness and substantial 42mm size are noted as significant, though the reviewer found the stealthy, dressed-down design grew on them. On balance, owners and reviewers rate the Squale Master highly for its exceptional build quality and legibility at its price point.
