From video reviewers

The Casio MDV-106 Duro's quartz movement demonstrates excellent accuracy. Its stainless steel case features surprisingly good finishing for its price point.

Momentum M20 DSS

Owners widely praise the Momentum M20 DSS for its extreme toughness and go-anywhere, do-anything dive watch persona, with many noting its appearance significantly exceeds online depictions. Reviewers and owners alike highlight its acceptable fit and finish for the price, double-domed sapphire crystal, and machined clasp. The 42mm case is considered a great size for those who prefer larger watches, contributing to its lightness and long-term usability. One owner reports the bezel insert lume pip snapped off multiple times, though replacements were provided free of charge.
