CHRONOMÈTRE BLEU

THE CHRONOMÈTRE BLEU OFFERS AN UNCLUTTERED APPROACH TO HIGH PRECISION, WITH IRREPROACHABLE CHRONOMETRIC PROPRERTIES. IT IS INNOVATIVE, WITH A 39 MM CASE MADE OF TANTALUM, A RARE DARK GREY METAL WITH BLUE OVERTONES, SO NAMED FOR THE “TORMENT OF TANTALUS” IN REFERENCE TO THE GREEK MYTHOLOGY. TANTALUM IS A METAL RARELY USED IN WATCHMAKING BECAUSE IT IS VERY HARD AND DIFFICULT TO FASHION (ITS FUSION TEMPERATURE IS 3016° AND ITS DENSITY 16.65 G/CM3). IT IS ALSO VALUED FOR ITS EXTREMELY HIGH RESISTANCE TO CORROSION AND WEAR, AND ITS BIO COMPATIBILITY.
