## Overall Watch Rating: 7.3/10.0

**Brand Metric (6.3/10.0)** - Alpina delivers dependable Swiss engineering comparable to Hamilton or Sinn in the high-premium segment.
**History & Innovation Metric (6.4/10.0)** - Drawing from Alpina's longstanding Startimer pilot legacy provides solid historical appeal, though it lacks cutting-edge advancements.
**Rarity Metric (6.4/10.0)** - Priced around $4,500 MSRP, it offers moderate exclusivity akin to other accessible Swiss chronographs.
**Material Metric (8.3/10.0)** - The 316L stainless steel case paired with AR-coated sapphire crystal ensures durable, high-end construction.
**Movement Metric (8.1/10.0)** - The in-house modified AL-372 automatic provides proven chronograph reliability on par with ETA 7750-based calibers.
**Complications Metric (7.7/10.0)** - The traditional three-subdial chronograph delivers practical timing utility benchmarked against mid-tier pilots.
**Functions Metric (7.2/10.0)** - Time, date, and chronograph coverage meets versatile daily needs like a Tissot PRS but with added heritage flair.
**Dials & Design Metric (7.8/10.0)** - The sunburst black dial with bold indices and lume excels in pilot legibility, rivaling Oris Aviators.
**Versatility Metric (7.4/10.0)** - Excels in casual sports and adventure settings as a pilot tool, though its size tempers formal adaptability.

## TPS Interpretation: Strong Value: This watch outperforms expectations for its price with robust materials and movement in a heritage pilot package.
## WM Collector Grade: B+
