The Casio Duro gives you the familiar pleasures of a dive watch—a rotating bezel, clear dial and screw-down crown—without making ownership a project. Enthusiasts love it because it gets those fundamentals right, with quartz practicality and a little personality from the marlin on the MDV-106 dial. Its 44mm case is substantial, though, so the question is less whether you like divers than whether you like this much watch on your wrist.
The distinction between the MDV-106 and MDV-107 is worth knowing: the latter drops the marlin branding while retaining the same basic dive-watch formula. Choose the former if that small fish is part of the attraction. On a used example, pay particular attention to the crown threads and bezel action; the crown should engage cleanly, and the bezel should turn counterclockwise with definite clicks. The mineral crystal can pick up scratches, too.
What owners love
- The dial is easy to read at a glance, with broad hands and clear markers that don't get lost against the background. Owners also like how the sunburst dial catches the light without looking flashy.
- The screw-down crown and 200m water resistance make it a watch owners happily wear swimming rather than leave on the shore. Long-term wearers often describe it as dependable and undemanding.
- The rotating bezel has a reassuring click and is genuinely useful for timing everyday things. It feels like a properly functional part of the watch, not just decoration.
Common Criticisms
- The supplied resin strap is a frequent complaint: it can feel stiff and less comfortable than the watch itself deserves. Swapping it is often the first change owners make.
- The lume is underwhelming, especially after the initial glow fades. Daytime legibility is much better than its ability to stay readable through the night.
- At 44mm, it takes up a fair amount of wrist space, and some owners find it too large despite liking the design. The mineral crystal also picks up scratches more readily than they'd like.
