# Tudor Black Bay Fifty-Eight 925 Review by A.I. WatchMetrics

## Watch Summary
The Tudor Black Bay Fifty-Eight 925 is a vintage-inspired luxury dive watch with a distinctive all-925 sterling silver construction including the 39mm case, unidirectional bezel with black lacquered engravings, and riveted bracelet, featuring a refined silver sunray dial with gilt snowflake hands, applied indices, and a date window at 6 o'clock beneath a domed sapphire crystal. It appeals to enthusiasts and collectors seeking elevated tool-watch heritage with precious-metal elegance and 200m water resistance, distinguished by its unprecedented silver-on-silver Black Bay design, robust lume, and T-fit clasp. Driven by the in-house automatic Manufacture Calibre MT5400 (COSC-certified) with 70 hours of power reserve and a 28,800 vph beat rate.

## Overall Watch Rating: 7.4/10.0

**Material Metric (9.4/10.0)** - Extensive 925 silver usage in case, bezel, and bracelet with premium brushing, polishing, and rhodium plating elevates it to near-haute levels, akin to Omega's gold-accented divers.

**Dials & Design Metric (9.3/10.0)** - The sunray silver dial with gilt accents and iconic Black Bay proportions delivers captivating vintage charm, benchmarked against Rolex Opaline dials for visual depth.

**Movement Metric (8.9/10.0)** - In-house MT5400 provides COSC accuracy, extended 70-hour reserve, and anti-magnetic silicon hairspring, surpassing many Sellita-based movements in entry-luxury competitors like Nomos.

**Versatility Metric (8.6/10.0)** - Compact 39mm sizing and silver's warm tone make it ideal for sports, casual, or semi-formal settings, more adaptable than bulkier steel divers from Blancpain.

**History & Innovation Metric (8.1/10.0)** - Drawing from 1958 Tudor divers with modern in-house COSC evolution, it mirrors the heritage trajectory of IWC's Mark series.

**Brand Metric (7.7/10.0)** - Tudor's Rolex-backed prestige and quality control place it firmly in entry-luxury, comparable to Grand Seiko's accessible excellence.

**Rarity Metric (6.4/10.0)** - Priced at $4,600 MSRP with solid but non-limited production, it offers moderate exclusivity versus microbrand one-offs under $2,000.

**Functions Metric (4.7/10.0)** - Core hours, minutes, seconds, and date deliver reliable daily utility, aligning with Seiko Prospex basics.

**Complications Metric (3.9/10.0)** - A straightforward date complication adds convenience without excess, similar to entry-level Longines HydroConquest models.

## Total Performance Score (TPS): 9.9

## WM Collector Grade: A+

## Performance Insights: Exceptional material, design, and movement elevate this to premium territory, offset by basic complications; it delivers A+ value at $4,600 versus an implied $8,400 performance equivalent.

## TPS Interpretation: Outstanding Value: This watch dramatically outperforms price-expected benchmarks in craftsmanship and heritage.
