Resonance Dual Time Stopwatch F. P. Journe





In 2010, FP Journe cel­e­brated the 10th anniver­sary of the famous stop­watch res­o­nance with a new col­lec­tion of watches. All mod­els in this col­lec­tion, includ­ing older divine mod­els, some­times entirely in pink gold or plat­inum and assorted dials, some­times with nice leather strap. Every­thing is done in per­fec­tion, to reveal the grace of the object and watch mak­ing prowess he has.

The move­ment, spear­headed the watch is a mechan­i­cal move­ment with man­ual wind­ing 750/1000 Rose Gold (18k) COSC, Man­u­fac­ture cal­iber 1499.2, which includes the famous res­o­nance mech­a­nism certified.

Found on the dial indi­ca­tion of hours, min­utes and small sec­onds on two sep­a­rate (Dual Time) and ringed dials. The power reserve is reversed to 12, inform­ing them of the hours that would have elapsed when the time comes assem­bles again.

The prin­ci­ple of res­o­nance stop­watch is extremely com­plex but it can be addressed, for the first time as well, as described by FP Journe brand itself:

When the body senses a vibra­tion, it absorbs energy and vibrates at the same fre­quency. The first is called the sec­ond exciter and res­onator, whereas the two pen­du­lums inside are alter­nately exciter and res­onator. Thus, when the arms are mov­ing, they come into sym­pa­thy by the res­o­nance effect and fric­tion in oppo­si­tion. Both gim­bals help each other, giv­ing them more iner­tia move­ment. This agree­ment is only pos­si­ble if the fre­quency dif­fer­ence from one to the other does not exceed five sec­onds per day com­bined on six posi­tions dif­fer­ence. Their set­ting is of extreme delicacy.

While an exter­nal dis­rup­tive move­ment affects the oper­a­tion of a con­ven­tional mechan­i­cal watch, this same dis­tur­bance in the case of the watch to res­o­nance, an accel­er­at­ing effect of the gim­bals as it slows down the other. Grad­u­ally, the two bal­ances come towards each other to find their point of agree­ment, elim­i­nat­ing the dis­rup­tion, result­ing in increased accu­racy. In other words, where a move­ment with a unique bal­ance that takes a shock accel­er­ated or slow, even­tu­ally get­ting ahead or behind in the indi­ca­tion of time, in a move­ment with these two bal­ances, one can com­pen­sate each other in crashes and to pro­vide extreme precision.
