Watches Review Center Report: If the wrist is a face plate surface, then this function has a jump reverse face, certainly the most abundant expression, each to a certain moment, an instant bounce back to square one pointer to give the players more crumble space. Speaking of inverse function of the watch jump in recent years have produced many of the watch factory are all kinds of retrograde watches, mechanical models of the menu, seems to have formed a particular trend.
Inverse function of the origin of dance, watch the development in the medium term will have to show creativity watchmaker use (about 1905 or so), but used in the watch, the first appearing in 1997 by an independent system of Zurich, Switzerland watch Division PaulGerber published in the BASEL watchs show a jump function with inverse watch Retrograde. This innovative design, immediately aroused the attention of many people and cause heated discussions, the next few years, many of the watch factory in response to market demand started to make the inverse function of the watch jump.
Inverse jump on the market today are used in features to date, week, hours, minutes, seconds and other display structures, however, if the reverse jump a week, sometimes the user will miss such a wonderful picture, it most likely show the beauty of inverse jump should be one minute or 30 seconds against the jump function. 30 seconds to reverse jump, the one day mechanical structure of the watch must bear the 2,880 times the bounce back action, the movement mechanism of the inverse of the jump components are quite frequent and the stress is enormous, so the design must be very focused on stability and can withstand great stress and other serious topic, by the rapid development of modern CAD design, these problems can be solved.
The principle of reverse hop mainly by bouncing cam (a vortex-shaped metal reeds) and back to the trackwheel movement back and forth between bar and the reaction resulted in a rebound phenomenon of instantaneous gear, as mentioned earlier the number of rebound very frequent, stress concentration is too large, repeated movement against the jump component, the case of metal fatigue and failure than the other functions of the mechanical structure is more likely to occur. Because bouncing back trackwheel rod cam and the interaction requires a return to block the power of media as support, the source of the power structure in the reverse jump is often used as a medium rod spring file, but the file bar spring force as a larger role in the moment and often have long retreated strong enough force or power instability, and excessive bouncing cam will also be the stress concentration arising from wear and tear, deformation, then reverse time jump second part will appear error, and most cases occur mostly late spring (that is, slow seconds).
In view of this, Zurich watchmaker Paul Gerber came up to replace the spring lever springs, this problem has been resolved. Because the springs from the back addition to the supply stability, the situation is almost the aforementioned loss does not occur. Strictly speaking up against the hop is a violation of the principle of the innovative mechanical design, for which components will be more prone to easy wear and tear circumstances. Although many people happy every day because you can watch the pointer from the frequent movement, and prefer to watch against the jump, but before purchasing such a watch, a more general response to the mechanical structure easier to watch failure, has a clear understanding of the.
