The Pilot 29.2430.4069/63.C813, seen from the bench

The Zenith Pilot Type 20 Extra Special (reference 29.2430.4069/63.C813) is a 45mm chronograph in titanium and bronze, designed after military aviation timepieces issued to French fighter pilots during World War II. It features the renowned Zenith El Primero 4069 column-wheel movement with 36,000 oscillations per second (10Hz), enabling precision to the hundredth of a second. The crown is positioned at 12 o'clock to avoid interference during flight. The 20mm lug width reflects the optimal proportions for this case size.
