The complexity of the construction process is what makes this chronograph unique. The 46 mm case of Chrono 4 Géant Full Injection uses a low temperature carbon diffusion treatment. This allows the carbon to penetrate the steel surface for 30 micrometers, thus producing a structural hardening.
With the increase of the steel’s hardness – the resistance to fatigue has greatly improved. The Diamond Like Coating gives the watch a particularly sporty and attractive look.
The black shade is extended to the chronograph push buttons and crown and the black dial, with black counters and red counter’s hands, features a circular metal plate. The name of the model – Full Injection – is engraved on the case-back. Water-resistant to 200 meters, this chronograph comes with a vertically sculpted rubber strap.
