This Tourbillon Souverain is part of the Tourbillon Nouveau (TN) series, launched by F. P. Journe in 2004. It is a complete redesign of the original Tourbillon Souverain, and only the placement and design of the tourbillon cage was retained; Journe removed the remontoire from view and added a deadbeat seconds complication in its place at 6 o'clock.
This Tourbillon Souverain TN is quintessentially Journe, both in its design language and movement. The textured silvery-grey dial is a smooth canvas, not distracting the wearer from the tourbillon cage at 9 o'clock, or the separate silvered guilloché dial that is used for the hours and minutes. The words ‘Invenit et Fecit’ are inscribed above the tourbillon (Latin for ‘Invented and Made’ or more literally 'Designed and built by F. P. Journe'), in classic F. P. Journe style - a nod to signing conventions of a century ago. Also inscribed are the words 'Remontoire d'Egalité' and 'avec Seconde Morte', denoting the added deadbeat seconds complication. At 12 o’clock, a power reserve indicator of 42 hours is displayed.
The natural deadbeat seconds is displayed at 6 o’clock, concealing the remontoire, which featured more prominently on the first Tourbillon Souverain. The term ‘Seconde Morte' or ‘deadbeat seconds’, is derived from the way in which the hand remains motionless, until the second has passed. More usually seen in 40mm, this watch has a diameter of 38mm, a slightly smaller size, that is very rarely seen in the series.
The Tourbillon Souverain TN is powered by the F. P. Journe calibre 1403, which is an 18k rose gold movement with Remontoir d'egalité, constructed with 25 jewels and a shock-absorber mechanism. It further features a straight-line lever escapement, and monometallic 4-arm balance with 4 timing weights, adjusted to 5 positions. It includes a self-compensating free-sprung flat balance spring. The movement is engraved 'Chronometre A Tourbillon', and it is decorated with Côtes de Genève.
