The Tourbillon Souverain represents François-Paul Journe's inaugural masterpiece: first model in F.P.Journe Invenit et Fecit Collection launched 1999, only tourbillon wristwatch combining remontoire d'égalité constant-force device with independent dead beat seconds. The Black Label edition reference TN, produced exclusively 2006-2015 for existing F.P.Journe owners through boutiques, elevates this emblematic timepiece through platinum construction and distinguished blackened gold dial with whitened guilloché silver subdials. This exceptional mechanism represents Journe's invenit et fecit philosophy—invented and made by François-Paul Journe—providing unique timekeeping performance in tourbillon still most accurate on market. In 2004 driven by thirst for timekeeping research and creative needs, Journe presented new generation Tourbillon Souverain with remontoire and dead beat seconds replacing existing Tourbillon Souverain with remontoire becoming collector's timepiece with about hundred produced giving even more sought-after status. The watch won Aiguille d'Or 2004 Geneva Grand Prix d'Horlogerie recognizing unprecedented tourbillon achievement. The mechanism uses remontoire or constant-force device valued for timekeeping performances, enriched with independent dead beat seconds system representing unique feature on contemporary wristwatch providing more accurate read of precise time. French term for independent seconds called seconde morte or dead beat seconds stems from fact that hand remains motionless—dead—for as long as second has not actually elapsed, hand thus indicating second only after it has actually past, jumping forward one full second with each tick rather than sweeping continuously. The watch traces lineage to centuries-long quest for isochronism: 15th century Jobst Bürgi creating first remontoire, 17th century Christiaan Huygens inventing balance-spring and pendulum making constant-force device temporarily obsolete, 18th century Age of Enlightenment requiring higher precision prompting Thomas Mudge and Robert Robin developing constant-force devices for marine chronometers and regulators. Making constant-force device complex and tedious caused almost entire 20th century abandonment except George Daniels, Anthony Randall, and Journe himself incorporating into pocket-watches before creating first wristwatch version with Tourbillon Souverain. What fascinates in constant-force principle is each watchmaker building one has own personal interpretation—only basic idea remains same.
The 40mm diameter case fabricates entirely from 950 platinum, employing two-piece construction with entirely polished surfaces. The case measures 9.9mm overall height accommodating Caliber 1403's 7.20mm movement height including raised tourbillon cage. Round form follows classic chronometer geometry, polished bezel flowing into mid-case, downturned lugs improving wrist conformity, screw-down exhibition caseback revealing spectacular 18k rose gold movement with tourbillon cage prominently displayed at 9 o'clock through sapphire crystal. The crown positions at 3 o'clock with two positions: position 0 disengaged, position 1 for manual winding requiring 20 turns of crown for full 42-hour wind, position 2 for time setting. Sapphire crystals front and back provide movement visibility showcasing beauty and sophistication of technical and aesthetic feat. Platinum represents most precious metal, F.P.Journe creating distinguished lacquered black dial personalizing further brand watches' elegance, Black Label Collection available only in F.P.Journe boutiques and espaces for existing F.P.Journe watch owners.
The dial employs blackened 18-carat gold base with whitened guilloché silver subdials secured by polished steel rings through F.P.Journe's patented technique creating distinctive identity of F.P.Journe chronometers. Hours and minutes subdial positions at 3 o'clock within whitened guilloché silver circle secured by polished steel screws, blued steel dauphine hands indicating hours and minutes off-center creating asymmetric composition. Dead beat seconds subdial positions at 6 o'clock within whitened guilloché silver circle secured by polished steel screws, blued steel hand jumping forward precisely one full second with each tick demonstrating independent dead beat seconds mechanism, seconde morte hand remaining motionless between ticks providing more accurate read of precise time. Retrograde power reserve indicator positions at 12 o'clock upper dial, semicircular scale showing 0 to 42 hours remaining power reserve with blued steel hand sweeping retrograde arc. Tourbillon cage prominently displays at 9 o'clock left side dial visible through aperture, one-minute rotation tourbillon with remontoire d'égalité constant-force device, golden bridges and cage contrasting against black dial creating spectacular visual centerpiece. Brand signature "F.P.JOURNE Invenit et Fecit" inscribes upper dial along with "Remontoir d'Egalité avec Seconde Morte" designation at lower dial establishing tourbillon with constant-force and dead beat seconds identity. Applied Arabic numeral hour markers at 12-3-6-9 positions in whitened finish. The composition creates unique asymmetric display: hours/minutes subdial at 3 o'clock, dead beat seconds subdial at 6 o'clock, tourbillon aperture at 9 o'clock, retrograde power reserve at 12 o'clock, demonstrating Journe's philosophy privileging function and legibility.
Caliber 1403 manual-winding movement fabricated entirely from 18k rose gold represents Journe's revolutionary tourbillon architecture combining three exceptional complications. The movement comprises 193 components without dial (218 cased on leather strap) measuring 32.40mm overall diameter, 32.00mm casing-up diameter, and 7.20mm overall height including tourbillon cage elevation. The tourbillon mechanism employs one-minute rotating cage compensating gravitational errors on balance, bridge and cage fabricated from 18k rose gold creating golden spectacle visible through dial aperture at 9 o'clock. Remontoire d'égalité constant-force device comprises secondary wheel assembled on lever swiveling concentrically to tourbillon cage, lever stopping principal wheel carrying second hand transmitting energy of barrel, whereas auxiliary spring or equalizing spring gives its energy to escapement, secondary wheel releasing once per second with repetition auxiliary spring re-fueled by principal wheel, ensuring constant linear force received by escapement assuring isochronism throughout power reserve. Patents EP 1 760 544 A1 and EP 03405772.9 protect remontoire and tourbillon innovations. Independent dead beat seconds mechanism jumps forward precisely one full second with each tick, hand remaining motionless between ticks, seconde morte providing more accurate read of precise time unique feature on contemporary wristwatch. Balance features four inertia weights, flat Anachron balance spring with Breguet overcoil providing paramagnetic properties and superior isochronism, pinned stud, free-sprung configuration, spring pinned to collet. Escapement employs 15-tooth escape wheel, 90-degree anchor fork. Balance vibrates 21,600 vph, traditional 3 Hz frequency. Balance inertia measures 11.00 mg·cm² with 52° angle of lift. Amplitude measures remarkable 280° dial-up at both 0 hours and 24 hours, demonstrating constant-force device effectiveness maintaining consistent amplitude throughout power reserve. Autonomy provides 42 hours power reserve displayed via retrograde indicator at 12 o'clock. Manual winding requires 20 turns of crown. Two-position winding crown enables winding in position 1, time adjustment via crown in position 2. The movement employs 26 jewels throughout. High-quality finishing: circular stripes on bridges creating decorative radial patterns, Geneva waves on baseplate providing traditional Côtes de Genève decoration, screw heads polished and bevelled, pegs with polished rounded ends, visible through sapphire caseback showcasing spectacular 18k rose gold movement with prominent tourbillon.
