# CUSTOM - Urkraft Casio Duro Submarliner Review by A.I. WatchMetrics

## Watch Summary
The CUSTOM Urkraft Casio Duro Submarliner is a boutique-modified version of the popular Casio MDV106 Duro quartz dive watch, redesigned as a close homage to the Rolex Submariner with a black dial featuring applied indices and Mercedes hands, unidirectional ceramic bezel insert, sapphire crystal, Super-LumiNova lume, brushed and polished 316L stainless steel case, and screw-down crown for 200m water resistance, targeting budget tool watch fans who want premium aesthetics and durability without luxury costs, powered by the reliable Casio 2784 quartz module.

## Overall Watch Rating: 4.4/10.0

**Versatility Metric (8.5/10.0)** - Outstanding versatility as a go-anywhere dive beater with easy 22mm strap swaps for casual, sports, or adventure use, matching entry-level Seiko Prospex models.
**Material Metric (8.2/10.0)** - Robust 316L stainless steel case paired with sapphire crystal and ceramic bezel delivers strong protection and premium feel on par with mid-tier tool watches.
**Movement Metric (5.3/10.0)** - The quartz movement offers excellent accuracy and no-wind reliability typical of high-performing Casio divers.
**Brand Metric (4.5/10.0)** - Casio's established mid-tier reliability gets a lift from Urkraft's low-volume custom appeal to modding enthusiasts.
**Functions Metric (3.5/10.0)** - Essential time, date, and dive bezel functions provide solid utility like other affordable quartz divers.
**Rarity Metric (3.5/10.0)** - Custom mod production adds moderate scarcity beyond the mass-market base Duro.
**Dials & Design Metric (3.5/10.0)** - Appealing Submariner-inspired layout with strong lume but limited originality, comparable to Pagani or San Martin homages.
**History & Innovation Metric (1.8/10.0)** - Minimal heritage or inventive elements as a derivative customization without notable contributions.
**Complications Metric (1.2/10.0)** - No true complications beyond basics, standard for entry quartz tool watches.

## Total Performance Score (TPS): 4.0

## WM Collector Grade: C

## Performance Insights: Strengths in versatility and materials make it a capable beater diver, while weaknesses in history, complications, and design hold back collector interest, yielding average value slightly above its implied price equivalent.

## TPS Interpretation: Average Value: The watch meets basic expectations for a budget modded diver with reliable build quality at its price.
