**Material Metric (9.6/10.0)** - Brushed and polished stainless steel paired with glareproofed sapphire both sides offers elite durability and finishing akin to Sinn instrument cases.
**Dials & Design Metric (9.2/10.0)** - Anthracite texture, applied indices, and signature rider tabs create a bold yet elegant pilot aesthetic comparable to the Zenith Chronomaster Sport.
**History & Innovation Metric (8.9/10.0)** - Aviation legacy since 1884 and pioneering automatic chronograph advancements stand shoulder-to-shoulder with the Omega Speedmaster's moonwatch heritage.

**Functions Metric (8.0/10.0)** - Core time, date, stopwatch, and 24-hour functions provide solid everyday utility like a standard Rolex Oyster Perpetual Date.
**Rarity Metric (7.4/10.0)** - Its mid-luxury pricing and steady production mirror the accessibility of non-limited Datejust models from Rolex.
