ASTRONOMIC SOUVERAINE

AFTER THE SUCCESS OF THE PROTOTYPE’S SALE AT THE ONLY WATCH AUCTION, F.P.JOURNE PRESENTS THE FINAL VERSION: ASTRONOMIC SOUVERAINE. IT IS A GRAND COMPLICATION WATCH IN A STEEL CASE, WITH TOURBILLON AND MINUTE REPEATER, WHOSE VOCATION IS TO RECALL A LONG-FORGOTTEN GESTURE. THAT OF LOSING ONESELF IN THE STARS IN ORDER TO BETTER FIND ONE’S WAY ON EARTH. THERE WAS A TIME WHEN THAT POETIC IDEA WAS NOT A PARADOX, BUT A SELF-EVIDENT TRUTH. AND LIKE THE INSTRUMENTS THAT WERE ONCE USED FOR THE OBSERVATION OF THE STARS, THE ASTRONOMIC SOUVERAINE IS ABOVE ALL A TOOL. BUT RATHER THAN OPENING A WINDOW ONTO THE CELESTIAL VAULT, IT CELEBRATES TIME IN ALL ITS GLORY.
