# Rolex Milgauss Review by A.I. WatchMetrics

## Watch Summary
The Rolex Milgauss is a distinctive sports luxury watch originally engineered in the 1950s for scientists and engineers requiring magnetic resistance up to 1,000 gauss, featuring the iconic orange lightning bolt seconds hand, Z-blue sunray dial with green sapphire crystal on the reference 116400GV, robust 40mm Oystersteel case, and powered by the in-house automatic Caliber 3131 with a 48-hour power reserve, appealing to professionals, collectors, and enthusiasts seeking a unique, under-the-radar Rolex with tool-watch credentials.

## Overall Watch Rating: 8.8/10.0

**Material Metric (9.9/10.0)** - Rolex's use of 904L Oystersteel, green sapphire crystal with anti-reflective treatment, and impeccable brushed/polished finishing rivals the best in luxury dive watches like the Submariner.

**Movement Metric (9.8/10.0)** - The Caliber 3131 delivers exceptional performance with Parachrom hairspring for antimagnetic protection, Paraflex shock absorbers, and Superlative Chronometer certification, surpassing standard automatics in reliability.

**Dials & Design Metric (9.7/10.0)** - The Z-blue gradient dial, orange lightning bolt hand, and refined Oyster proportions offer timeless yet bold aesthetics comparable to the most collectible Rolex sports models.

**History & Innovation Metric (9.5/10.0)** - With roots in 1956 as the first antimagnetic watch for professionals and modern updates like the lightning hand, it stands alongside historic icons like the original Explorer.

**Cohesiveness Metric (9.5/10.0)** - Seamlessly integrating into Rolex's Oyster lineup with consistent quality and theme of scientific precision, it exemplifies brand-wide excellence.

**Brand Metric (9.2/10.0)** - Rolex's century-plus legacy of precision and prestige benchmarks the luxury tier, akin to Patek Philippe in global recognition.

**Versatility Metric (8.9/10.0)** - Suitable from boardroom to weekend adventures with 100m water resistance and comfortable bracelet, it edges out dressier models like the Datejust for everyday wear.

**Rarity Metric (8.5/10.0)** - Discontinued production and niche appeal keep secondary availability limited compared to high-volume Rolex staples like the Datejust.

**Functions Metric (8.2/10.0)** - Delivers reliable timekeeping, date, and lume visibility on par with entry-luxury divers but without extras like GMT.

**Complications Metric (6.0/10.0)** - Basic date window provides solid utility but lags behind complication-heavy peers like the Sky-Dweller.

## Total Performance Score (TPS): 6.2

## WM Collector Grade: B+

## Performance Insights: Excels in materials, movement, and design for enduring appeal, tempered by simpler complications, offering strong collector value below implied pricing.

## TPS Interpretation: Good Value: The watch delivers premium craftsmanship and innovation exceeding baseline expectations at its market price.
