WACTCHS
But the real star here is the remontoir in the two going trains. In the original movement, although both balance wheels Sinn Replica oscillate at the same amplitude, that amplitude also dipped at the same time as the power reserve of the watch winds down. What the remontoir does is that it brings constant torque to the escapement, and the balance wheels will oscillate at the same constant amplitude as long as the remontoir is engaged.
There are essentially two kinds of remontoir, one has an additional hairspring, and in the case of Journe’s watches, it comes with a spring bladed mechanism. The long blade-shaped spring provides a direct linear force to each of the two balance springs on the new Resonance so that they remain isochronous for 28 hours. The movement has a Replica Panerai Luminor Chrono Flyback power reserve of 42 hours, but because the remontoir takes energy from the mainspring to recharge and there are two remontoirs to charge, the function lasts only 28 hours. But not to fret. Even after Ulysse Nardin Replica Watches the remontoirs disengage, the balances will still be oscillating because of resonance, in a more constant amplitude than if there was only a single balance wheel.
The model is available in a case in platinum or in 18K 6N red Gold in 40 or 42mm diameter. There are two versions of the dial: one in 18K white gold and another in 6N red gold. The two sundials are in whitened silver guilloché clous de Paris. The watch comes with a choice of leather strap or gold or platinum bracelet.
The Influence of F.P. Journe’s Résonance
The Chronomètre à Résonance was the first wristwatch to utilise the physical natural resonance without any mechanical transmission phenomenon like a double pendulum or a double balance. Journe’s predecessors include 17 century Dutch scientist Christiaan Huygens, followed by the likes of Antide Janvier and Abraham-Louis Breguet in the 18th century, who all have timepieces based on the resonance principle.
