Reviews

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

Certina DS Super PH500M

Owners widely praise the Certina DS Super PH500M for its retro dive watch aesthetic, good legibility, and value, with many highlighting its striking orange dial and secure bezel lock. The Powermatic 80.611 movement is reported as consistent and accurate, with one owner noting +2/+3 seconds per day performance. The watch is considered tough and offers good specifications for its price. However, some find the 43mm case and 15mm thickness substantial, potentially wearing large on smaller wrists, and one reviewer notes the crystal retaining ring can be a scratch magnet. Overall, owners and reviewers rate the Certina DS Super PH500M highly for its vintage-inspired design and excellent value proposition.

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.
