The Pilot 49.4001.3620/63.I001, seen from the bench

The Zenith Pilot Type 20 Chronograph 49.4001.3620/63.I001 is a contemporary evolution of an aviation icon from World War One. The 40 mm high-tech ceramic case houses the legendary El Primero 3620 caliber, a sophisticated mechanical chronograph beating at 36,000 vibrations per hour. The 22 mm lug width is specifically proportioned to the ceramic case mass and dial geometry, offering scratch resistance superior to steel and absolute impermeability without galvanic corrosion.
