The Duro (Casio calls it the Marlin in some markets) is the cheapest way to get a proper dive-watch layout: a steel case, a unidirectional bezel, a screw-down crown and 200 m water resistance. Its dial and handset look much more expensive than the watch costs, which is why enthusiasts often call it the best value in watches.
Who it’s for
Swimmers, beach-goers and anyone curious about dive watches who wants to try the style before spending real money.
Buying tips
- At 44 mm it wears large. The lug-to-lug length matters more than the case width, so check it against your wrist.
- The stock resin strap is basic. A rubber or NATO strap transforms the watch.
- Prices swing with demand. When the tracker shows a dip, it’s a good time to buy.
