F.P.Journe - Tourbillon Souverain Bleu for Only Watch 2015

F.P.Journe Tourbillon Souverain Bleu for Only Watch 2015; The Tourbillon Souverain Bleu for Only Watch 2015 is the first tourbillon watch with a case made entirely in tantalum, a rare dark grey metal with blue overtones.

The unique timepieces created for the Only Watch 2015 Charity Auction (Geneva, 7 November 2015) by 43 top brands have started to flow and one of the most stunning watch unveiled so far is a special version of the Tourbillon Souverain designed by F.P. Journe for the occasion.

The Tourbillon Souverain Bleu for Only Watch 2015 is the first tourbillon watch with a case made entirely in tantalum, a rare dark grey metal with blue overtones. Difficult to manipulate due to its high density, tantalum is extremely resistant to corrosion and wear.

The 40 mm case frames an eye-catching blue chrome dial which changes character according to the colour of incident light. The hours and minutes sub-dial at 3 o'clock is symmetric to the tourbillon at 9 o'clock while the 42-hour power-reserve indication at 12 o'clock visually counter-balances the independent seconds display at 6 o'clock.

The in-house F.P. Journe movement is made of 18 karat rose gold, and is fitted with a remontoire - a constant force device - enriched with an independent seconds system for a more accurate read-off of time. The French term for "independent seconds", called "seconde morte" or "dead-beat seconds", refers to the fact that the hand remains motionless ("dead") for as long as the second has not actually elapsed. fpjourne.com
