# Doxa Sub 300 Review by A.I. WatchMetrics


## Watch Summary
The Doxa Sub 300 is an iconic professional tool dive watch featuring a distinctive cushion case, bold orange sunray dial with applied markers and sword hands, targeting saturation divers, underwater professionals, and history-focused collectors; its unique no-decompression bezel, exceptional legibility, and COMEX heritage set it apart, powered by an automatic Sellita SW200-1 movement offering a 38-hour power reserve.

## Overall Watch Rating: 6.8/10.0

**Brand Metric (6.5/10.0)** - Doxa commands respect as a niche Swiss dive specialist, on par with Sinn for dedicated tool watch enthusiasts.

**History & Innovation Metric (9.2/10.0)** - Revolutionary as the first watch for helium saturation diving in 1967, it surpasses most contemporaries in professional legacy like early Blancpain divers.

**Rarity Metric (5.3/10.0)** - Unlimited production at its $2,200 price keeps it accessible, akin to standard Omega Seamaster 300M models.

**Material Metric (9.0/10.0)** - Robust 316L stainless steel, AR-coated sapphire crystal, and ceramic bezel rival premium tool watches like the Rolex Submariner.

**Movement Metric (6.4/10.0)** - Dependable Sellita SW200-1 delivers ETA 2824-level reliability found in Hamilton Khaki or Tissot Seastar divers.

**Complications Metric (1.5/10.0)** - Pure three-hander with date lacks extras, matching basic autos like the Seiko 5 Sports.

**Functions Metric (6.2/10.0)** - Core time, date, and dive-timer bezel perform solidly like fellow pro divers such as the Citizen Promaster.

**Dials & Design Metric (9.3/10.0)** - Timeless orange dial, cushion profile, and lume-charged legibility outshine generic sports watches like the Invicta Pro Diver.

**Versatility Metric (8.2/10.0)** - Thrives in aquatic adventures and casual settings but trails slimmer pieces for dressier occasions, similar to other beefy divers.

## Total Performance Score (TPS): 4.0
## TPS Interpretation: Fair Value: The watch offers legendary styling and dive-ready construction that compensates for its straightforward mechanics at this price.
## WM Collector Grade: C
## Performance Insights: Shines in heritage, aesthetics, and materials as a collector's tool watch, but modest movement and functions deliver middling value against its $2,200 implied price.
