Last F.P.Journe creation, the CHRONOMETRE BLEU proposes a new approach of high precision, with perfect chronometric virtues. The CHRONOMETRE BLEU is innovative with its 39 mm case made for the first time of Tantalum, a rare dark grey metal with blue overtones. Tantalum is a wonderful metal but rarely used in watchmaking as it is hard and very difficult to manipulate, due to its very high fusion temperature of 3800° and a density of 16.6. Tantalum is also precious as it is highly resistant to corrosion and wear.
