The famed Son­nerie Sou­veraine per­haps is the most mas­ter­ful watch that F.P. Journe has ever pro­duced.

THAT FO­CUSES ON BEAUTY AS MUCH AS IT DOES SIM­PLIC­ITY AND

DURA­BIL­ITY.

If there was ever a ‘beater minute re­peater’, it is the Son­nerie Sou­veraine. Com­pleted in around 2005, as of 2013, only about 30 of the watches have been pro­duced. This par­tic­u­lar piece is F.P. Journe’s per­sonal model, and he wears it ev­ery­where - even if he has a dif­fer­ent model watch he is pro­mot­ing that is worn on his op­po­site wrist.

The Grande Son­nerie watch with a minute re­peater is the most com­plex of horo­log­i­cal cre­ations, one that de­mands the very ut­most in both tech­ni­cal and artis­tic vir­tu­os­ity for the watch­maker in charge of its assem­bly. In the past, it has al­ways been risky to use a Grande Son­nerie watch. The slight­est er­ror – for ex­am­ple, ad­just­ing the time while the watch is chim­ing – could se­verely dam­age the watch’s del­i­cate mech­a­nisms. There­fore, the first en­try in F.P.Journe’s spec­i­fi­ca­tion book for this watch was: make the watch so that an eight-year-old child can ma­nip­u­late it safely with­out dam­ag­ing it. To meet this chal­lenge, he had to con­struct a move­ment based on new me­chan­i­cal prin­ci­ples. Thus, ac­cord­ing to the brand’s motto, ten patents tes­tify to the ‘In­venit’ of this work of watch­mak­ing art, while the ‘Fecit’ took six years of re­search and de­vel­op­ment”.

The priv­i­lege of a Grande Son­nerie watch is to trans­late time into mu­sic. The Mai­son Journe who be­came an ex­pert in the mas­tery of the res­o­nance strik­ing watch is aware of the im­por­tance of acous­tic waves in the art of the time mea­sure­ment. It demon­strates its mas­tery when it comes to re­trans­mit time into sounds.

The sound sig­nal emit­ted by the ex­tra-flat gongs of 3/10 of a mil­lime­tre has been treated with as much im­por­tance as the func­tion mode of this mech­a­nism which re­quires a par­tic­u­lar ham­mer strike. In­deed, the strik­ing weight of the ham­mer of the Grande Son­nerie is of 0.3 grams. This force is, to give an es­ti­mate, be­tween 10 and 15 times less than that used to strike a clas­si­cal minute re­peater.

How­ever, be­cause the acous­tics work has been par­tic­u­larly metic­u­lous and the tech­ni­cal so­lu­tions per­fectly adapted to this type of com­pli­ca­tion, the Son­nerie Sou­veraine F.P.Journe pro­duces a bet­ter sound than any equiv­a­lent

strik­ing time­piece. Also, a new se­lec­tion mode by the 4-hour but­ton al­lows you to choose be­tween three op­tions: Grande Son­nerie, Petite Son­nerie and Si­lence. The pusher at 2 o’clock ac­ti­vates the Minute Re­peater on demand.

For such a beau­ti­ful watch, F.P.Journe has ex­cep­tion­ally aban­doned pre­cious me­tals for its cases, Gold and Plat­inum for a no­ble cause, to en­sure the best pos­si­ble strik­ing tones that make op­ti­mal use of the crys­talline struc­ture of Steel.

The Son­nerie Sou­veraine re­ceived the Aigu­ille d’Or prize at the Grand Prix d’Hor­logerie de Genève in 2006. It was also named Watch of the Year at the Grand Prize of Ja­pan in 2006.

Bin­au­ral is a record­ing tech­nique per­formed to cre­ate a three-di­men­sional sound. For the bin­au­ral record­ing of the Son­nerie Sou­veraine, F.P.Journe used ar­ti­fi­cial ears with mi­cro­phones. In the choice of com­po­nents up to the shapes and pro­por­tions, ev­ery­thing is de­signed in this de­vice to re­pro­duce a sound as close as pos­si­ble to hu­man ex­pe­ri­ence.

For this horo­log­i­cal world Pre­miere, F.P.Journe in­vested the EPFL ane­choic cham­ber in Lau­sanne. The EPFL is one of Switzer­land’s two fed­eral poly­tech­nics school, and the most in­no­va­tive and pro­duc­tive sci­en­tific in­sti­tu­tion in the world. All the walls (in­clud­ing the floor) of the 200 m2 ane­choic cham­ber is en­tirely cov­ered with 1-me­ter high glass wool di­he­dral, al­low­ing an op­ti­mal ab­sorp­tion of sound.

To delve into the heart of Son­nerie Sou­veraine me­chan­ics, F.P.Journe’s ap­proach was to reach the soul of this marvel of tech­ni­cal­ity. You can dis­cover the bin­au­ral sound of the Son­nerie Sou­veraine F.P.Journe on www.fpjourne.com. Re­mem­ber to wear head­phones to live this unique ex­pe­ri­ence truly. It is a unique ex­pe­ri­ence which pro­vides a to­tal im­mer­sion in the heart of this ex­cep­tional strik­ing watch’s move­ment.
