"Back the needle," the watch and its features

"Back the needle" refers to the direction of the watch dial needles. Most of the watches, the time when the table clockwise, counterclockwise rotation of the watch is a pointer; but the individual watches contrast, when put in the table clockwise, clockwise rotation of the watch is a pointer, but this is called "down dial needle, "estimate refers to its distinctive meaning.
    Watch dial needles line of gear a few, when the rotary table to time, the table on the handle shaft front end is a square table, and set on top of it lying round, cooperate with them have an inner four holes, so lying round be driven by rotation. Lying round in the watches of the gear is quite special, because only it is "lying" was placed horizontally, and it has two different ends of the tooth, called the "straight teeth" and "helical", with straight teeth on the dial needles, and for the helical winding.
    Lying round also called "clutch wheel", like a car clutch, as it is a stall, at least two tranches, and more can be fourth gear. In addition to winding dial needle, watches also require other additional features of the adjustment, pull the clutch it stalls parts control and positioning, to achieve reliable gear meshing with different purposes.
    When the table to completely pull out, will lie straight-tooth wheel sprocket meshing with the needle on the dial, and then through the cross-power transmission to the wheel when the wheel and sub-round (small center wheel), watch hours of pointers are installed precisely on them, so the pointer can be driven and rotated.
Form a "back the needle," because the dial needle is more of a department drive wheel, the wheel can be called a "dial-mediated needle wheel" or "off the dial needle wheel", nor is deliberately doing this often and watches movement to the design of the main drive gear in the form and layout of plywood. Watch some of the eccentric drive will be "back the needle", and its form with a needle from the bias leads to the second axle, and this leads to precisely the point position in the Department of dial needles. If the film there because the wheel diameter, manipulated, or how out of reach when driving, but also need to add a referral round.
    Watch the French early Mustang (YEMA) FE140C movement, as well as Switzerland AS/ST1950 movement, are typical "back the needle".
"Back the needle," watch and grade the quality of travel time has nothing to do, good or bad, just need to dial needle to adapt can be fleeting. You want, there are over bicycle wheel brake it down, put the car there is cross-file it, which are due to design considerations, and the "back the needle," the use of the watch will not have any awkward.
    Some people get a dial to determine the direction of the needle as the basis for the authenticity of the watch brands such as Rolex 3135 movement, (including dual calendar Rolex 3155 movement, but the Rolex with 2135 and 2235 the female form is not back the movement pin) off the table because the Department generally will use ETA28 movement, then a reversal of the direction of both a dial needle is completely different, this is indeed the voice of experience it can be considered effective.
