A new version of Eberhard & Co's iconic Chrono 4 sports a total black look. The steel case of the "Full Injection" model undergoes a treatment that makes the carbon penetrate through the surface to a depth of 30 micrometers, thanks to low-temperature diffusion, hardening the metal and making it more resistant to shocks and wear. The black colouring with 'gunmetal' shades is given by the DLC - Dianoir treatment. This is a limited edition of 500 pieces
