# Sinn 104 I St Sa White Review by A.I. WatchMetrics

## Watch Summary
The Sinn 104 I St Sa White is a timeless German pilot watch blending classic aviation aesthetics with modern tool-watch robustness, featuring a pristine white lacquered dial with bold luminous indices and hands for superior legibility, a bead-blasted stainless steel case, and the workhorse Sellita SW 200-1 automatic movement offering 38 hours of power reserve, targeted at enthusiasts who value precision engineering, magnetic resistance, and a 200m water resistance rating in a versatile 41mm package.

## Overall Watch Rating: 7.3/10.0

**Material Metric (9.4/10.0)** - The bead-blasted stainless steel case paired with double-sided antireflective sapphire crystal delivers exceptional durability and clarity, on par with top dive watches like the Omega Seamaster.

**Cohesiveness Metric (9.5/10.0)** - As a standalone piece, it exemplifies Sinn's unified pilot philosophy with flawless execution across elements.

**Dials & Design Metric (9.0/10.0)** - The clean white dial with precise indices and balanced proportions offers outstanding legibility and subtle elegance, rivaling iconic IWC pilot dials.

**Versatility Metric (8.8/10.0)** - This pilot excels across casual, office, sports, and adventure scenarios thanks to its legible dial and robust build, much like a versatile Tudor Black Bay.

**History & Innovation Metric (8.2/10.0)** - Sinn's Luftwaffe heritage and proprietary technologies like the dehumidifying capsule and magnetic field protection elevate it above standard pilots.

**Brand Metric (7.1/10.0)** - Sinn holds strong in the high-premium tier for its no-nonsense German engineering and cult following among tool watch collectors.

**Functions Metric (5.5/10.0)** - Core timekeeping with date provides reliable everyday utility, akin to entry-level Swiss automatics.

**Rarity Metric (5.8/10.0)** - At its price point and moderate production, it strikes a balanced exclusivity similar to other limited-run tool watches.

**Movement Metric (5.3/10.0)** - The Sellita SW 200-1 delivers solid reliability but lacks the refinement of in-house calibers like those in Grand Seiko.

**Complications Metric (4.0/10.0)** - The simple date window adds basic utility without overwhelming the clean pilot layout.

## Total Performance Score (TPS): 9.9

## WM Collector Grade: A+

## Performance Insights: Excels in material quality, design, and brand heritage while movement and complications are average, delivering outstanding value well below the implied fair price.

## TPS Interpretation: Outstanding Value: The watch vastly overperforms expectations with premium build and heritage at a mid-tier price.
