# 11 Watch Collection - Casio (100%) Review by A.I. WatchMetrics ## Collection Summary This collection assembles eleven identical Casio Duro (MDV106-variant) dive watches into a hyper-focused fleet of budget tool watches, emphasizing relentless utility, 200m water resistance, reliable quartz movements with approximately 3-year battery life, and unbeatable affordability around $70 each, perfectly suited for the hardcore user who rotates multiples through extreme wet and rugged conditions without a hint of variety. **"Duro Duplication Fleet"** ## Overall Collection Rating: 4.0/10.0 **Brand Metric (5.0/10.0)** - Casio delivers solid mid-tier reliability akin to Citizen or Seiko in the accessible tool watch arena. **History & Innovation Metric (4.2/10.0)** - The Duro's rise as a cult budget diver adds niche appeal, but it trails established icons in heritage and novel engineering. **Rarity Metric (1.2/10.0)** - Mass-produced at low price points, these watches flood the market like entry-level Seiko divers. **Material Metric (4.0/10.0)** - Stainless steel cases and mineral crystals offer decent toughness for the cost, heavily dinged for zero material diversity across the set. **Movement Metric (3.5/10.0)** - Dependable quartz accuracy shines for low-maintenance use, but utter lack of movement variety tanks the collection score. **Complications Metric (0.5/10.0)** - Purely basic time and date functions with no added complexities whatsoever. **Functions Metric (4.5/10.0)** - Solid dive-ready basics including bezel timing and date window meet everyday tool needs adequately. **Dials & Design Metric (5.0/10.0)** - Clean, legible diver dials with effective lume perform well for the price, undermined by repetitive uniformity. **Versatility Metric (5.5/10.0)** - Tough divers handle sports, adventure, and casual duties superbly, lacking breadth for broader collector appeal. **Cohesiveness Metric (6.5/10.0)** - Unmatched thematic unity as an all-Duro armada, balanced against diversity deficits. ## Total Performance Score (TPS): 4.0 ## TPS Interpretation: Fair Value: The collection aligns with baseline expectations for ultra-budget tool watch multiples, prioritizing raw utility over sophistication. ## WM Collector Grade: D ## Performance Insights: Cohesiveness and brand standouts provide fleet-like reliability, countered by dismal rarity, complications, and diversity; outstanding value versus the sub-$100 implied average price. ## Collection Type by Style - Diver: 100% - Sports: 100% - Tool: 100% - Adventure: 90% ## Collection Type by Movement - Quartz: 100% ## Collection Strengths - Unparalleled value density at ~$70 per tough 200m diver. - Extreme rotation capability for high-abuse aquatic pursuits. - Cult status as the quintessential affordable go-to dive watch. ## Ideas for Improvement 1. Diversify with variant Duro colors or bezel inserts for visual interest without breaking theme. 2. Incorporate a mechanical diver like a Seiko SKX for movement contrast and upgrade path. 3. Add one premium tool watch (e.g., Oris Aquis) to elevate overall caliber and aspiration. ## Downsizing Advice With eleven indistinguishable pieces, aggressively downsize to 2-3 for practical rotation—sell the surplus on secondary markets to fund meaningful diversity, avoiding the redundancy trap that stifles collection growth. ## Watch by Watch Summary Casio Duro (70) #1: Rugged 44mm stainless steel diver with 200m WR, quartz reliability, and stellar lume value.
