great majority the person will thought of adornment very naturally, after all, the function in"is negative to jump" is very personal independence of conduct, although we can not let the time converse,let the watch pour to turn several turns aren't what difficult matter.These is also a lot of artificial this big books the book sell a point especially, but go against to jump form to appear reason before people's eyes in fact, at the beginning, not for satisfying people on the desire of "return to in the past" of spirit.Because the watch goes against to jump because of adopting of device, the area of dial can significantly narrow, this also increases other functions to provide space for watch if not adopt negative jump of this kind of equip, all needles have to do on a shaft, the size of a lot of watches will significantly increase, and the diameter of dial even will be more even big than your wrist son.But after have negative jump of the design, the design space of wrist form got to biggest release.Now, don't say that the second hand can carry out negative jump, even minute, hour, date and weeks can carry out negative jump.We at up expected to once enumerate a Fan gram graceful treasure that Le Pont ever des Amoureux, is also adopted a negative design for jumping.

what is negative to jump form?

"negative jump" mean that the watch points a kind of method of needle movement, and tradition does a that the circumference revolves the needle is different, the form needle of "negative jump" type is to walk one way, be designation after engraving a full distance of one degree, pointing the needle will in a twinkling return back to engrave one degree point of departure and then repeat new process.Therefore, "is negative to jump" type's engraving a degree is respectively side of, and point the stalk of needle all generally and do on the edge of dial, the radian that engraves one degree noodles is lower than 180 degrees, typical model of between 120~150 degrees.

concerning "is negative to jump" the type still have another parlance, be be called "fly to return".However, "fly to return"(flyback) is just a kind of parlance for being established by usage, but strictly speaks "fly to return" type what to should point is to account stop-watch, be it point all of the needles to return zero:00, is also a moment finished of."Fly to return" and"negative jump" is from the function look about, but it inner part of the machine structure is totally different from the work principle.The differentiation lies in:"Negative jump" type points needle is walk curve, returning of"negative jump" type's returning is an auto finished of;But"fly to return" the type account the needle of stop-watch is to turn a turn to walk circle, its return zero to need to move a button operation, can complete still from two or so directions.For example the J12 of Chanel is mysterious to fly to return wrist form of figure 9, this wrist form had the complicated function of three nicety:Tuo flywheel, fly to return minute hand and equipment to leave the form hat of matching the system, is also a world fanciful combination for the first time, worth write in an extensive and deep clock of dictionary in.

"is negative to jump" the type originally belong to an ancient clock design and about appear on a kind of special pocket-watch for the first time in 200 year agos.This kind of pocket-watch is at that timetreasure Ji do, its needle dish the noodles was fan-shaped, therefore was called fan-shaped form. After 100 years, E?Koehn promotes this device, and by dint of was negative to jump a second hand to apply for patent.From that time on, the figure then multifarious emergence that goes against to jump is in each function dial.Now, went against to jump to equip to then become numerous manufacturers the son is the spoiling of favor, basically among the form style any needle functions all have already carried out negative jump.At present in the market of negative jump function to use to show date, week respectively, , cent, second etc..However, there is a small minor faults here, particularly is for those adoption date negative jump the wrist form of design to say, just goes against to jump for a month once, will miss a fascinating appearance that the needle in a twinkling replies on doing not be careful.Therefore, mostly manufacturer more favor in let minute and the second hand"is negative to jump" get up.Make a show of most easily negative jump of beautiful of, still 30 pair negative jump function, is also from two 30 negative jump a needle to complete an operation for 1 minute.

negative jump of principle more simple, do work in fact have no so difficult, certainly, we aren't to make a video frequency, if you make me chase this kind of principle if write out with the writing, also have popular request to easily understand, that will I close life.

internationalthe Portuguese Tuo flywheel is negative to jump wrist of form

someone for example and ever explained like this negative jumped the principle of form:

" STEP 1:Is Wo-like in shape to bounce cam with call back a pole control negative jump a minute hand or second hand of Wo-like in shape the direction bouncing agreeable clock of cam carry on, but call back a pole to negative clock direction agreeable wheel gear headway.Is negative to jump second hand or minute hand on the noodles dish, to fan-shaped engrave the bottom of degree to carry on.

STEP2:The time wheel gear after completing sheds off be bounce a cam to march forward the top of volute form, and call back a pole to walk to the wheel gear most at this time what time, volute bounce a cam will with call back pole occurrence to shed off condition.At this time noodles dish ascend negative jump second hand or minute hand have already walked to fan-shaped engrave the bottom of the degree and carry.

STEP3:After the occurrence that is negative to jump to operatively return to play to shed off condition, call back a pole side of visit silk to will call back a pole and bounce a cam to in a twinkling bounce home position recoil.At this time noodles dish of negative jump second hand or minute hand, would return to order at first, carried on square one again suddenly of machine operation."

but, if don't make clear what is "being Wo-like in shape to bounce a cam" and"call back a pole" etc. science word, changed anyone, all perhaps will be incomprehensible while facing these words.If you are really interested in to is negative to jump the structure of form, can register Chinese clock net to search to arrive more detailed diagram text to explain.In fine, concerning negative jump of principle, remember 1:00 enough, at negative jump form in, the most decisive place lies in one to bounce a cam, thwart see past, live a hat like person in Rome.Is exactly its existence, so as to let each big fairy on the dial in a twinkling return.But, on the principle although is plain to easily understand,want to want to perfectly carry out not that easy.The problem comes from 2:00.

1.Being negative to jump the inner part of form to bump shot number of times is a lot of, with the problem that this will produce metal fatigue.Bouncing the cam time number of times for playing is very multifarious, at return to play of that for an instant, in response to the concentrated dint lead greatly, therefore negative jump module while again and again exercising, the situation of metal fatigue and breakdown compares with the machine structure of other functions to more easily take place.This is like a kid's son to want to think bye a wire in the curved hand, don't need to cost much energy, the demand is in the same place of wire again and again bye several bottoms are all right.

2.The time that is negative to jump form return is also time of demand of, this insignificant time long-last accumulation the bottom go, will result in an error margin.You can probably imagine among the wrist form of a wire bye as to it's after bending will his module produce how of the influence not is to produce a loss, an occurrence form to change, at this time contrary jump time of a part and then will appear an error margin, and the situation of greatly parts of emergence much for delay to bounce is also slow second.

certainly, this a pair problem the root is a floating cloud in the clock masters eyes.Pass the adoption more excellent metal material, lower the kinetic energy of bumping the shot, can good solution drop the problem of metal fatigue.But the error margin then is in a twinkling more simple to reply of time is certain, so time that needs to be computed very to in a twinkling reply every time, then take into to revise in the middle of designing all right.Therefore, truely concern in the master heart of, is how pass negative jump, carry out more pomps in the limited space.
