# 11 Watch Collection - Casio (100%) Review by A.I. WatchMetrics ## Collection Summary This collection is an extreme monoculture of eleven identical Casio Duro (MDV-106) quartz dive watches, delivering unwavering focus on budget-friendly tool-watch utility with 200m water resistance, rotating bezels, date windows, and excellent lume across a unified blue-wave dial theme. Perfectly cohesive for the backup-obsessed practicalist or dive enthusiast on a shoestring budget, it highlights unbeatable reliability and value but sacrifices all diversity for sheer quantity. **"Duro Fleet Overload"** ## Overall Collection Rating: 4.5/10.0 **Cohesiveness Metric (8.5/10.0)** - Achieves submarine-like uniformity in a pure dive-watch theme, surpassing most collections in thematic lockstep despite zero variety. **Dials & Design Metric (5.5/10.0)** - The signature wave dial, bold indices, and potent lume deliver above-average legibility and charm, on par with entry-level Seiko divers. **Versatility Metric (5.5/10.0)** - Excels as a rugged daily beater for water activities and casual wear, matching the flexibility of classic tool watches like the Timex Ironman. **Functions Metric (5.2/10.0)** - Offers reliable timekeeping, date, and dive bezel utility solid for the price, comparable to basic Citizen Promasters. **Movement Metric (4.8/10.0)** - Quartz reliability ensures accuracy and no-wind convenience, but lacks diversity akin to a Seiko 5 Sports assortment. **Material Metric (4.7/10.0)** - Stainless steel cases with mineral crystals hold up well for diving, though repetition heavily docks breadth versus mixed-material sets. **History & Innovation Metric (4.5/10.0)** - Draws on Casio's quartz legacy with a cult-favorite design, but trails innovators like the original Seiko 62MAS. **Brand Metric (3.0/10.0)** - Casio provides dependable entry-level accessibility like Timex, without the prestige of mid-tier names like Hamilton. **Complications Metric (2.0/10.0)** - Barebones with no standout features beyond basics, falling short of even simple chronographs in Tissot divers. **Rarity Metric (1.0/10.0)** - Mass-produced budget staple widely available, as common as the Casio F91W. ## Total Performance Score (TPS): 4.0 ## TPS Interpretation: Fair Value: The collection squeezes strong cohesion and tool utility out of its rock-bottom pricing, though duplication drags overall performance. ## WM Collector Grade: D ## Performance Insights: Cohesiveness and dials/design provide standout strengths well above expectations, while rarity, complications, and breadth suffer from repetition; delivers decent redundancy value against an implied ~$70 per-watch price point. ## Collection Type by Style - Diver: 11 watches (100%) - Tool: 11 watches (100%) - Sports: 11 watches (100%) ## Collection Type by Movement - Quartz: 11 watches (100%) ## Collection Strengths - Unrivaled backup reliability for high-risk activities like diving or fieldwork. - Iconic Duro design and lume offer enthusiast appeal at fraction-of-cost pricing. - Perfect thematic purity for a "fleet" mentality without decision fatigue. ## Ideas for Improvement 1. Diversify with alternate Duro colorways (e.g., black dial or Pepsi bezel) for subtle visual variety. 2. Incorporate complementary quartz divers from Citizen or Seiko to broaden tool-watch scope. 3. Add one mechanical piece like a Seiko SKX for movement contrast and upgrade path. ## Downsizing Advice Eleven identical watches offer massive redundancy but zero functional gain beyond three, so pare down to 1-2 primaries plus backups to reclaim ~$600+ for exciting diversification without losing dive readiness. ## Watch by Watch Summary 1.
