# Sector Spanish Made Review by A.I. WatchMetrics

## Watch Summary
The Sector Spanish Made is a no-nonsense dive watch proudly manufactured in Spain, boasting a hefty 44mm stainless steel case, flat sapphire crystal, unidirectional aluminum bezel, and an extraordinary 500m water resistance powered by a reliable ISA quartz movement with about 50 months of battery life, targeting budget adventurers and spec chasers who want pro-level dive capability without luxury pricing.

## Overall Watch Rating: 4.7/10.0

**Versatility Metric (8.5/10.0)** - With 500m water resistance, screw-down crown, and rubber strap compatibility, it outshines typical budget divers like the Casio MDV106 in everyday rugged use from beach to boardroom.
**Material Metric (8.2/10.0)** - Stainless steel case with sapphire crystal and solid screw-down caseback delivers better build quality than most sub-$400 quartz divers, akin to entry Oris specs.
**Dials & Design Metric (5.5/10.0)** - The black dial with luminous indices and bold markers offers solid legibility but feels generic next to more original designs from Seiko Prospex.
**Brand Metric (4.5/10.0)** - Sector holds steady as a mid-tier Spanish maker like Citizen, reliable for practical watches but lacking the global prestige of Omega.
**History & Innovation Metric (4.0/10.0)** - Over 50 years of Spanish watchmaking with niche high-WR quartz innovation places it on par with established affordable brands like Laco.
**Movement Metric (3.8/10.0)** - The ISA quartz is accurate and low-maintenance like a standard ETA quartz but trails mechanicals in enthusiast appeal compared to Seiko NH35.
**Functions Metric (3.5/10.0)** - Basic time and date functions perform adequately for daily needs, matching entry-level quartz like Timex Ironman but without extras.
**Rarity Metric (2.5/10.0)** - Common production and accessible pricing make it as ubiquitous as mass-market Seikos on the secondary market.
**Complications Metric (1.5/10.0)** - Lacking advanced features beyond date, it lags far behind complicated divers like the Citizen Promaster Eco-Drive.

## Total Performance Score (TPS): 9.9

## WM Collector Grade: A+

## Performance Insights: Excels in material durability and versatility with pro dive specs, but held back by generic design and basic quartz movement, delivering outstanding value versus its $2,500 implied price.

## TPS Interpretation: Exceptional Value: The watch punches way above its weight with dive-ready construction and specs that rival pricier competitors.
