Zenith El Primero Range Rover Special Edition Automatic Chronograph 24.2040.400 The watch also feels functional, being lightweight for a large watch. The case is 42mm in diameter and 12.75mm high – standard for the El Primero – but weights just 40g, less than a third of the ordinary steel model. That’s because the case is aluminium, a light but soft metal, that’s undergone electrolytic oxidation. This creates a thin but scratch resistant ceramic layer on its surface, making it more robust than ordinary aluminium. The material is similar to the “Composite” cases used by Panerai. Inside is the calibre 400B, the standard El Primero chronograph movement, but with the Range Rover logo on the rotor (which also repeats on the case back).
