# Casio Duro Review by A.I. WatchMetrics

## Watch Summary
The Casio Duro (reference MDV106) is a legendary budget-friendly dive watch featuring a robust stainless steel case, unidirectional rotating aluminum bezel, highly legible black dial with strong lume, and 200m water resistance, powered by a reliable quartz movement with roughly 3 years of battery-powered power reserve, perfectly suited for novice divers, daily beaters, and value hunters seeking tool-watch toughness without breaking the bank.

## Overall Watch Rating: 6.5/10.0

**Dials & Design Metric (8.5/10.0)** - The bold indices, sword hands, and classic dive bezel deliver exceptional legibility and timeless appeal, on par with higher-priced Seiko divers.
**Versatility Metric (8.5/10.0)** - Its rugged yet compact profile transitions seamlessly from beach adventures to office casual, surpassing many single-purpose fashion watches.
**Material Metric (7.5/10.0)** - Stainless steel construction with mineral crystal offers commendable durability for active use, better than plastic alternatives but shy of titanium luxury cases.
**Movement Metric (7.5/10.0)** - Quartz precision and maintenance-free operation outperform basic mechanicals in entry-level Timex or Invicta models.
**History & Innovation Metric (7.0/10.0)** - Casio's quartz revolution heritage elevates it above generic brands, though the Duro sticks to proven diver formulas like early Seikos.
**Functions Metric (7.0/10.0)** - Time, date, and dive bezel timing provide all essentials for practical use, comparable to core features in Omega's affordable Seamasters.
**Brand Metric (5.4/10.0)** - Casio anchors mid-tier reliability much like Citizen, excelling in tough, affordable tool watches.
**Complications Metric (6.3/10.0)** - Simple date and rotating bezel add utility without excess, matching mid-tier Citizen Eco-Drive divers.
**Rarity Metric (1.0/10.0)** - Mass production and sub-$100 pricing make it commonplace, similar to the Seiko SKX007's widespread availability.

## Total Performance Score (TPS): 8.5

## WM Collector Grade: A-

## Performance Insights: Excels in design, versatility, materials, and movement reliability while rarity and complications lag; delivers outsized value well above its $70 street price.
## TPS Interpretation: Outstanding Value: The Duro vastly overdelivers on tool-watch prowess and durability relative to its modest price point.
