MDV106
A proper no-nonsense dive watch for remarkably little money.
The Duro delivers serious dive-watch capability for remarkably little money. Its 200 metres of water resistance and screw-down crown are hard to fault at this price. The large case and basic resin strap are the main compromises.
+ Exceptional capability for the price

− Large case and basic stock resin strap
Why it made our list
The Casio Duro earns its place at the top of our under $150 guide because it concentrates the budget on the things that actually matter. The case is stainless steel, the crown screws down and the watch is rated to 200 metres of water resistance. Those are meaningful features on a watch that can often be found well below the limit of this guide.
Its appeal goes beyond the specification sheet. The Duro has the straightforward proportions and visual language of a traditional dive watch without trying too hard to look more expensive than it is. The black dial is clean, the rotating bezel gives the watch genuine sports-watch character and the simple quartz movement makes it an easy watch to own.
There are compromises. Mineral glass is less scratch resistant than sapphire, the finishing is understandably basic and the supplied resin strap is one of the clearest reminders of the price. The 44.2mm case also makes the Duro a difficult recommendation for smaller wrists. Even so, the underlying watch delivers enough substance that these compromises are unusually easy to accept.
Design & wearability
There is no getting around the Duro's size. At 44.2mm across and 48.5mm from top to bottom, this is a substantial watch. The relatively restrained 12.1mm thickness helps, but buyers with smaller wrists should still expect plenty of wrist presence.
Visually, the simplicity works in its favour. The black dial, large markers and familiar dive-watch layout make the Duro immediately readable, while the red seconds hand adds just enough colour to prevent the design from becoming anonymous. It looks purposeful rather than decorative, which suits the character of the watch.
The standard resin strap does the job, but it is also where the budget construction is most obvious. It lacks the suppleness and substantial feel of a better rubber strap. A quality aftermarket rubber strap is therefore one of the easiest upgrades you can make and can noticeably improve how the Duro feels on the wrist.
Casio
Casio was founded in Japan in 1946 and entered the watch business decades later, eventually becoming one of the most recognisable names in affordable electronic timekeeping. The brand built much of its reputation on practical watches designed around reliability, accessibility and function.
The Duro represents a different side of that philosophy from Casio's famous digital watches. It is a simple analogue sports watch, but the priorities remain familiar: useful specifications, dependable quartz timekeeping and a price that keeps the watch accessible to almost anyone.
Our verdict
The Casio Duro is not impressive because it hides its low price particularly well. Look closely and the compromises are easy to find. The mineral crystal is basic, the resin strap feels inexpensive and the case will simply be too large for some wrists.
What makes the Duro special is how little those compromises affect its core purpose. The stainless steel case, screw-down crown and 200-metre water-resistance rating give it genuine everyday capability, while the quartz movement makes ownership almost effortless.
If you want refinement, compact dimensions or mechanical interest, there are better choices in this guide. If you want the greatest amount of practical watch for the least amount of money, however, the Duro is exceptionally difficult to beat. Replace the stock strap with a better rubber option and the package becomes even more convincing.
