Double Chasing Needle Measure The Distance Between Thunderstorm And Yourself

When the second moving body reaches the target point, pressing the timing button will stop the chronograph second hand, and the time it points to is the time consumed by the other moving body. If the timing of both hands is within one minute, the time difference can be directly calculated. If it exceeds one minute, the time difference can be obtained by combining the minute hand chronograph dial usually on such watches. Jian Fu saw Split Seconds. If it is in the pre-chronograph state, the central hour hand, minute hand, and second hand are all in the same position, and they do not feel that it is different from the ordinary third hand. However, if the watch is laid flat and viewed from the side, it is found that the second hand is two overlapping. Looking at the table side, in addition to a crown, there are usually one or two additional buttons, one of which is an independent button for the second hand.

Principle of two needle chase
The double-tracking hand is a kind of chronograph, and it is also the most complicated chronograph. There are two types of chasing the second hand and the minute hand, of which the chasing second hand is the most common and practical. It can record the movement time of two or more moving bodies in sections through the simultaneous movement of two chronograph seconds hands and their separate stops. Especially when the exercise time is within 60 seconds, the difference between the time consumed by the two moving bodies can also be displayed intuitively.

Generally speaking, the double-tracking watch is equipped with two to three buttons to help achieve the chronograph function. When you press the timekeeping button, the two seconds hands move together. At this time, if you do not look closely, it still looks like a hand is moving. When the first moving body reaches the target point, press the push-button, the second hand will suddenly snap Stopped, and the chronograph second hand still advancing at a constant speed. At this time, you can record the time spent by the first moving body according to the time indicated by the second hand.

When the second moving body reaches the target point, pressing the chronograph button will stop the chronograph second hand, and the time it refers to is the time consumed by the other moving body. At this time, the two second hands each occupy one place, and the existence of the ‘dual chasing hands’ is immediately apparent.
If the timing of both hands is within one minute, the time difference can be directly calculated. If it exceeds one minute, the time difference can be obtained by combining the minute hand chronograph dial usually on such watches.
Similarly, if you do not use the chronograph second hand to count time in the second time, but continue to use the chronograph second hand, some dual-secondary models also provide this function, provided that the number of timing points required by multiple moving objects The interval is slightly longer, and the user of the watch must also be quick-sighted.

复杂 Complicated process with high cost
‘Compared to ordinary chronographs, the double chase hands have more fun to play because of one extra chase hands,’ said Liu Xingli, a senior watch expert. ‘It has all the functions of ordinary chronographs.’ For example, ordinary chronographs The distance measurement function of the stopwatch, the dual chase dial can measure two distances at the same time. For example, everyone likes to use a chronograph to measure the distance between thunderstorm and themselves. Double tracking needles can measure the different distances between thunder and lightning. However, just as measuring the thunder and lightning behavior of the two places is ‘too busy’, the situation of the dual chase watch is also slightly awkward.
‘Strictly speaking, the double-tracking hand watch is the most difficult to make. It is more difficult than the three famous complex models of tourbillon, three-question, and perpetual calendar. Similarly, only a few masters can make it. High. ‘Watch culture scholar Chang Wei told reporters,’ Under the same brand, the double chase watch is two-thirds or even double the price of ordinary chronographs. It belongs to a relatively high-end positioning. ‘Its The complexity of the construction can be seen from the fact that the movement is one to two millimeters thicker than the ordinary chronograph.

At the same time, on the consumer’s side, most consumers still recognize the dual tracking needle as a ‘sport watch’, so not buying expensive prices leads to lower market demand, and those who do not have this will generally not buy. ‘And the wear rate of the movement of the double-tracking watch is relatively large, which will increase the maintenance cost for the brand, such as the number of maintenance points.’ In addition, the high production cost, it is difficult to mass-produce, producing the double-tracking watch There are relatively few brands, and the frequency of new products is relatively low. The promotion of its movement and structure is relatively low.

But from the perspective of collection, the double-tracking watch is a good investment, especially the double-tracking watch produced by Patek Philippe, Vacheron Constantin, Glashütte and other brands. In the late 19th and early 20th centuries, the double-stalling pocket watch of the initial era was even more rare. In addition, the use of a self-produced movement rather than a double-tracked watch improved on a universal movement is also very precious, Blancpain, Ruibao, IWC, Omega, Zenith all have such models.
