F.P. Journe，吸引及罕有，鉭金屬腕錶，“Chronomètre Bleu”，編號552-CB，約2013年製

The Chronometre Bleu stands out from the Souveraine collection by the use of tantalum for its case. Rare and extremely hard, the metal is highly corrosion-resistant but also incredibly difficult to machine and finish. F P Journe meets this challenge by creating a case entirely polished in tantalum. With its unique icy grey colour with a bluish hint, the case further enhances the beauty and elegance of the blue chrome dial. With a movement superbly executed in solid gold, this watch is the epitome of understated elegance and luxury.
