The Centigraphe Souverain represents François-Paul Journe's world premiere achievement: first wristwatch in world equipped with single hand-wound movement measuring elapsed times from one-hundredth second to 10 minutes across three subsidiary dials. The Black Label edition, produced between 2010 and 2017 exclusively for existing F.P.Journe owners through brand boutiques, elevates this groundbreaking chronograph through platinum construction and distinguished black dial with lacquered finish. The reference CT executes Journe's philosophy creating mechanical chronograph unlike any other—spectacularly converting 6 km/h walking pace to 36,000 km/h through integrated tachometer scales, theoretically timing objects moving approximately 1/3000th speed of light. The watch originated from meetings between Journe and Jean Todt (godfather of Centigraphe) through ICM Foundation, discussing ideal chronograph for car racing world, prompting Journe to revisit 15-year-old research on exponential chronograph demonstrating three hands revolving different speeds provided good starting base. Development incorporated research on chronograph pushers, power balance questions, requirements, energy loss, utilizing patent registered for Sonnerie Souveraine plus two additional patented innovations concerning motricity. The watch displays central hours and minutes, one-second chronograph hand at 10 o'clock making complete revolution per second on scale marked hundredths of second enabling 1/100th second measurement, 20-seconds chronograph hand at 2 o'clock completing tour every 20 seconds, 10-minutes chronograph hand at 6 o'clock completing tour every 10 minutes, technical prowess achieving 80-hour power reserve chronograph stopped and 24-hour reserve chronograph running. The watch won Aiguille d'Or 2008 Geneva Grand Prix d'Horlogerie recognizing unprecedented chronograph achievement. Journe committed donating 30% profits from each Centigraphe sale to ICM (Institute Brain and Spinal Cord Paris) with no time limit, supporting medical research fighting Alzheimer's, Parkinson's, Multiple Sclerosis alongside Professor Gérard Saillant, Luc Besson, Jean Réno, Jean Todt, Michelle Yeoh, Michael Schumacher.
The 40mm diameter case fabricates entirely from 950 platinum, employing two-piece construction with entirely polished surfaces. The case measures 10.1mm overall height accommodating Caliber 1506's 5.60mm movement height. Round form follows classic chronograph geometry, polished bezel flowing into mid-case, downturned lugs improving wrist conformity, screw-down exhibition caseback revealing 18k rose gold movement through sapphire crystal. Patented ergonomic rocker arm chronograph control positions at 2 o'clock case band replacing usual buttons flanking crown, rocker enabling start/stop/zero functions through single ergonomic control perfectly fitted to wristwatch design. The crown positions at 3 o'clock with three positions: position 0 disengaged, position 1 for winding, position 2 for time setting. Sapphire crystals front and back provide movement visibility. Platinum represents most precious metal, F.P.Journe creating distinguished lacquered black dial personalizing further brand watches' elegance.
The dial employs blackened 18-carat gold base with three whitened guilloché silver chronograph subdials creating dramatic contrast, red lacquered steel chronograph hands contrasting against rhodium-plated steel time hands. Central hours and minutes position dial center using rhodium-plated steel dauphine hands, applied Arabic numeral hour markers at 12-3-6-9 positions creating railroad-style chapter ring. The chronograph subdials each feature dual scales: inner red time scale and outer black tachometer scale converting time units to speeds. One-second chronograph subdial positions at 10 o'clock upper left, red lacquered steel hand completing revolution per second, inner scale marked 0-100 hundredths of second enabling 1/100th second readout, outer tachometer scale indicating speeds with 36,000 positioned facing 10 on hundredth-second scale theoretically enabling timing of objects moving 36,000 km/h (approximately 1/3000th speed of light or well above rocket escape velocity into low-level orbit). The 100th second hand may be stopped anywhere along one-second journey even between two divisions enabling fractional reading, achieved by vertically disengaging pinion from escapement creating braking effect. Twenty-seconds chronograph subdial positions at 2 o'clock upper right, red lacquered steel hand completing revolution every 20 seconds, inner scale divided into seconds, outer tachometer scale indicating corresponding speeds. Ten-minutes chronograph subdial positions at 6 o'clock lower center, red lacquered steel hand completing revolution every 10 minutes, scale graduated for 10 minutes with tachometer scale showing speeds corresponding to 20-second markers enabling precise speed calculations—kilometer traveled in three minutes 40 seconds represents 16.4 km/h speed. Brand signature "F.P.JOURNE Invenit et Fecit" inscribes dial alongside "Centigraphe" designation establishing chronograph identity. The composition creates comprehensive chronograph display with integrated tachometer functionality converting walking pace 6 km/h to extreme velocities 36,000 km/h.
Caliber 1506 manual-winding movement fabricated entirely from 18k rose gold represents Journe's unprecedented chronograph architecture. The movement comprises 284 components without dial (324 cased with strap) measuring 34.40mm overall diameter, 34.00mm casing-up diameter, and 5.60mm overall height. The chronograph mechanism employs patented configuration effectively isolating chronograph from timekeeping function meaning balance amplitude remains unaffected when chronograph running—separate chronograph train driven directly from mainspring independent of timekeeping train. The chronograph hands driven by two different wheel trains themselves driven from mainspring center utilizing system patented for Sonnerie Souveraine: one-second counter and 20-seconds counter driven by two wheel trains on either side of single intermediate wheel driven by barrel arbor, separate train also driven by barrel arbor drives 10-minutes hand. The 100th second mechanism employs wheel mounted on escape wheel (fourth wheel of going train) releasing arbor to which hand fitted, seconds driven by going train from barrel and by chronograph train energy transmitted via barrel arbor. Patented rocker arm control at 2 o'clock case band enables ergonomic start/stop/zero operation replacing traditional pushers. Return-to-zero mechanism employs hammer levers acting on snail cams for 20-seconds and 10-minutes hands, 100th second hand stopped at zero by beak protruding from pinion pressing lever blocking chronograph train. Free-sprung balance adjusted by four inertia weights vibrating 21,600 vph, traditional 3 Hz frequency. Anachron balance spring provides paramagnetic properties, mobile stud holders, pinned GE stud, spring pinned to collet. In-line lever escapement with 15-tooth escape wheel. Balance inertia measures 10.10 mg/cm² with 52° angle of lift. Amplitude measures 320° dial-up at 0 hours, dropping to 280° dial-up at 24 hours, healthy readings indicating efficient energy transmission. Barrel features maintaining power system ensuring driving force remains constant during winding. Autonomy provides 80 hours power reserve chronograph stopped, 24 hours chronograph running, impressive achievement for complex chronograph mechanism. The movement employs 50 jewels throughout. Base plate receives circular graining creating textured surface, bridges display circular stripes, screw heads receive mirror polishing with chamfered slots, pegs finish with polished rounded ends, straight-grained steelwork, high-grade decoration throughout visible through sapphire caseback.
