F.P.Journe « Tourbillon Souverain Bleu » Only Watch

F.P.Journe participates for the first time to ONLY WATCH charity auction in order to support the scientific research to fight against Muscular Dystrophy (AMM). A unique watch is created especially for the occasion, the « Tourbillon Souverain Bleu ».

It is also the first time ever that a tourbillon is made with a case entirely in Tantalum. The very astonishing blue chrome dial reflects like a mirror and its color changes according to light. Its F.P.Journe movement in 18K rose Gold features the renowned remontoire (constant force device) and the dead beat second.

The ONLY WATCH charity auction will take place in Geneva on 7 November 2015.
