The Chrono 4 Géant collection is being enhanced with a new super-cool total black edition: Chrono 4 Géant “Full Injection“. The timepiece, that perfectly combines technique and aesthetical elegance, is produced in a limited series of 500 pieces.
The complexity of the construction process, which makes this chronograph even more precious, allows in fact for only a limited production. The 46 mm case of Chrono 4 Géant “Full Injection” is particularly remarkable for the use of a special treatment consisting in advanced low temperature carbon diffusion. This allows the carbon to penetrate the steel surface for 30 μm (micrometers), thus producing a structural hardening. With the steel’s hardness increase, the watch-case wearresistance and fatigue-limit are improved. Afterwards, the beautiful black colour is obtained thanks to the treatment DLC – Dianoir® - Diamond Like Coating – which, by providing the steel case and buckle with a black coating, gives the watch a particularly sporty and attractive look.
