A Ruthenium Tourbillon Souverain, 1 of 99 examples made. Created between 2001 and 2003, the Ruthenium Collection was a final send-off to brass movements and one of very few individually numbered limited productions. This Ruthenium Tourbillon features an early reference ‘T’ architecture with an opened one-second remontoir d’égalité, a design which has clearly evolved directly from the very first FP Journe wristwatch ever. The mechanical and aesthetic drama of the gunmetal-tone Ruthenium Tourbillon Souverain have seen it become one of the most coveted FP Journes ever made.
