Common outer labeling of common chronograph cufflinks outer function can be divided into three kinds, namely, the flow meter, distance meter and pulse meter, use as follows: Figure Omega Speedmaster Space Walk 40th anniversary cufflinks circle figures is the general timing cufflinks marked the most common, and its main function is to be used to calculate a hour of work done (to complete a unit of time less than one minute), for example, to the calculation of the car within an hour to finish the mileage from the start time, finish one kilometer, stop cufflinks, if the second hand stopped at 30 seconds at the outer digital control 120, that is, to cufflinks shown such speed in one hour to finish the 120 km, which is 120 kilometers per hour, so many people directly to this feature as a speed meter; but it range of applications not only can calculate the distance per hour, for example, to calculate the fold. When it comes to the social environment of the personnel training, Kong thought that the attention and support given by the relevant cufflinks industry is far from enough.
A paper cranes to be time-consuming 45 seconds, corresponding to the outer 80, that is, to cufflinks to show that such a speed, an hour to complete the 80 paper cranes; the same reasoning can be applied in many cases, distance meter Telemeter. The distance meter suggests that it is to calculate the distance, how to count? Take education for example, China now has about more than 40 colleges and vocational schools to open a cufflinks design major. For example, see the lightning, start time, stop when you hear the sound code cufflinks, control digital distance meter, you can learn at about the distance and lightning on the battlefield, soldiers can thus determine the critical strike points with their distance. Its principle is to use the speed of light and the speed of sound speed difference from the speed of light, 300,000 kilometers per second, see lightning or blasting, almost incident at that time; the speed of sound per second, however, only 330 meters.
 It can be engaged to audio reached the time to calculate the distance between the two terms of 330 meters per second, the speed of sound calculation, the voice can convey nearly 20 kilometers per minute ranging period of 60 seconds at 20 km scale. Among the nearly 5,000 students in the school, part of the graduating students has transferred to other cufflinks industries. Of course, the speed of sound because of humidity, wind direction, and a variety of reasons such as change, this is only an approximate reference value. Pulse count, of course is used to calculate the pulse, cufflinks paragraph of this only in Athens, for example, the top mark of 30 under pulse measurement baseline pulse rate calculated from the activation of cufflinks, the number to 30, it immediately stop the code cufflinks to control pulsometer digital, you can know the number of pulse per minute.
However, before using the first note of the label on the pulse meter, some are 15 pulse for benchmark units, so as long as necessary to stop the code count 15 cufflinks; the same principle, but cleverly different. The number is far from satisfying demands of the industry of cufflinks. Quartz cufflinks according to the movement and use, battery life of 1-2 years. The high-end three-pin quartz cufflinks has a battery will be exhausted prompted seconds beating the exception that every four seconds, hop, and remind you of the need for timely replacement of batteries, if not promptly replace the battery may cause battery leakage and damage to the cuff internal parts. Some customers have several pieces of cufflinks, and usually do not wear order to power saving and pull out the cufflinks crown cufflinks stop and go, cufflinks face look cufflinks stop and go, in fact, the battery continues to discharge.
