Three question marks, that is, three question marks, can be read by the watch's three different kinds of sounds. Three questions can be issued three different sounds, respectively, "hour" "carved" "points", of which the bass tone is time, such as 4 "when, when, when," is 4:00. Followed by engraving, usually with high and low bass, such as: "jingle, jingle, jingle", that is, three minutes, which is 45 minutes. Next, the report is high pitch. "Bite, bite, bite, bite, bite, bite", 6 ring is 6 minutes, then this shows the time is 4:51. In the field of advanced watches, three asked timekeeping, calendar, tourbillon and is best described as the most advanced craftsmanship of the complicated hand-made technology. The function of the minute repeater is more complicated than ever because it requires a large number of parts and is extremely complicated to run and extremely challenging the complicated craftsmanship of hand-made watches. Three asked the composition of the timing part of the movement are: 1.Hour Rack, time rack; 2.MinuteRack, reported racks; 3.Secondary MinuteRack, the second minute rack; 4.Snails, Snail wheel; Hock, Hook, 6. Detent Pins, Ratchet Pin, 7. Activation Lever, Lever 8. Hourhammer, Hour Hammer, 9. Minute Hammer, Minute Hammer. Questionnaires have extremely sophisticated mechanical devices that must convert the time display into a series of chimes that express hours, minutes and minutes. Three question-table chain spring first pull the vertical operation of the key, to accumulate the energy required for timekeeping. In the meantime, hour, quarter and minute toothpicks have also been put on a clockwork, ready to enter the timekeeping position. At start-up, the energy released by the chain winding spring is supplied to the speed regulator, which operates on the principle of centrifugal force, keeping the rate of hammering constant, the two hammers striking bass, treble and bass . Three questions in general table, the case has a button or dial handle, press (move) it, you can hear the "Ding Dong Ding Dong," the voice time. In order for the watch to accurately report the complete time, it is usually necessary to apply some force when dialing the handle, because the process of pushing the handle is full, and it is also a process in which the clockwork is full of energy. In 1676, British watchmaker Edward Barlow invented a rack-and-pinion mechanism. In the 1780s, Daniel Quare, another British watchmaker, further refined and patented the two-way spring-loaded mechanism. The safety device he invented was only able to sound the time signal when the spring-loaded mechanism was fully activated. Later, he made a half-minute questioning table, from then on the type of pocket-spring pocket watch is gradually increasing. Spring Timekeeping - In 1783, Breguet produced the clockwork of the clocks, so often with crisp sounds in his works, it also brought new developments to the two timepieces. In 1891, Audemars Piguet invented an ultra-small movement with a diameter of 18 mm and a minute repeater function. By the early twentieth century, the basic mode of starting the questionnaire was to have a long dial on the side of the case, which was able to make a sound when it was pushed to the end to avoid unnecessary activation. This is also the credit for the safety device invented by Daniel Quare. Three questions gradually into the consumer's field. Tianjin seagull watch factory in 2006 the first to launch domestic two questioning table (timekeeping, carved). 2007 seagull successfully developed China's first three watches. Beijing Watch Factory in 2008 to celebrate the 50th anniversary of the establishment of the launch of "China Tourbillon three question marks", has become China's most complicated domestic production of watches. The world's limited 20, rose gold material, priced 350,000 yuan.
