More about F. P. Journe Chronometre Resonance Platinum / Silver Dial 40MM Deployant

This is a platinum F.P. JOURNE CHRONOMÈTRE À RÉSONANCE Dual Time. This chronometer has resonance controlled twin independent movements – two escapements working together – a radical design that took twenty years of research. It has a two-body, polished, solid, case with a transparent back and 6 screws. The side and top crowns are engine-turned in "cordes de Marseille" texturing; the crown at 12 o'clock winds both movements, independently setting the hours and minutes of each twin subsidiary guilloche silver dial. The crown at 4 o'clock synchronizes both seconds hands. The dials have printed Arabic numbers for hours and minutes, with two independent oscillators. A combined power reserve with an indicator energizes both time zone displays; a subsidiary seconds sub-dial has zero reset. There is a railway minute outer track and Journe's exclusive blued steel hands. The 8.8mm thick case, dial, and movement are all signed.

This F.P. JOURNE CHRONOMÈTRE À RÉSONANCE Dual Time has a mechanical in-house produced manual winding caliber 1499-2 movement. It's constructed with 36 jewels, fausses cotes decoration, a shock absorber, and twin straight-line lever escapements. The bridges and plates are 18K red gold, and the resonating engine keeps both movements synchronized. It includes twin beryllium 4-arm balances with 4 adjustable timing weights, and self-compensating free-sprung balance springs, with both independent trains on a single plate. one escapement is fixed to a small platform that pivots around the second wheel with a rack-and-pinion mechanism that adjusts the distance between the two balances in order to find the most efficient synchronized position. It oscillates at a frequency of 21,600 vph.

The F.P. JOURNE CHRONOMÈTRE À RÉSONANCE Dual Time was introduced in 2002, and it won the Watch of the Year jury award in Japan in 2003; it received the grand complication prize at the Grand Prix d'Horlogerie de Geneve in 2010.
