# Doxa Sub 300 Beta Review by A.I. WatchMetrics

## Watch Summary
The Doxa Sub 300 Beta is a professional dive watch reissuing the legendary 1968 original, characterized by its distinctive cushion-shaped case, vibrant orange sunray dial with applied markers and beta sword hands, targeting serious divers, saturation diving enthusiasts, and collectors who value historical tool watches. Unique features include a helium escape valve, unidirectional ceramic bezel with Super-LumiNova inserts, exceptional legibility, and 300m water resistance, powered by the Sellita SW200-1 automatic movement with 38 hours of power reserve.

## Overall Watch Rating: 6.8/10.0

**Brand Metric (6.8/10.0)** - Doxa commands respect as a Swiss dive specialist with over 130 years of heritage, on par with enthusiast favorites like Oris or Zodiac.

**History & Innovation Metric (9.2/10.0)** - As the first saturation dive watch from 1968 used by COMEX professionals, it delivers iconic historical impact rivaling the Blancpain Fifty Fathoms.

**Rarity Metric (5.2/10.0)** - With unlimited production and a mid-tier price, it prioritizes accessibility over the scarcity of limited-run divers like the Omega Great White.

**Material Metric (9.0/10.0)** - 316L stainless steel case, ceramic bezel insert, domed sapphire crystal with dual AR coating, and helium valve provide pro-level build quality matching modern Rolex Submariners.

**Movement Metric (7.0/10.0)** - The Sellita SW200-1 automatic offers reliable 28,800 vph performance and 38-hour reserve, comparable to the ETA 2824 clones in Tudor Rangers.

**Complications Metric (0.0/10.0)** - Pure tool-watch focus with no added complications keeps it simple and functional like classic Seiko 62MAS divers.

**Functions Metric (6.5/10.0)** - Hours, minutes, seconds, date window, and rotating dive bezel deliver essential pro-diving utility on level with Citizen Promasters.

**Dials & Design Metric (9.5/10.0)** - The bold orange dial, cushion case, beta hands, and full Super-LumiNova treatment create a legible, vintage-inspired icon akin to rare 1960s prototypes.

**Versatility Metric (8.2/10.0)** - Thrives in sports, adventure, tool, casual, and collector roles with NATO/rubber straps, surpassing many divers in everyday adaptability.

## Total Performance Score (TPS): 9.9
## TPS Interpretation: Exceptional Value: The watch dramatically overdelivers on heritage, design, and materials relative to its price, making it a steal for dive enthusiasts.
## WM Collector Grade: A+
