However, after the shock wave in the quartz, mechanical watches more than ten years into a downturn, many traditional watch factory exit thus come to grief. Overall downturn in the industry, by simplifying the design to achieve a lower cost, and Lemania 5100 movement ETA 7750, played a somewhat messianic role. Not only the savior, but also opened up a new era - in the past, due to its relatively high cost, time movement often appears only in the high-priced watches. But since the advent of two uneducated, low-cost chronograph models can be achieved, chronograph watches also increasingly gaining in popularity since. There is no doubt that, until today, ETA 7750 can still be regarded as its price segment of the king, the presence of a large number of derivative models describing the family's prosperity. And, as a basis for the movement were from low to high adoption of various brands. Use some plastic parts of the Lemania 5100 Although exit, but because of its good potential for earthquake reconstruction, and design in the big time on the minute hand to bring the dial legibility, making it still serving in the NATO. Easy to produce, easy to maintain good travel time, durable, great potential for the second transformation, which is fundamental to the success to build a ETA7750 reason. However, when mechanical watches keep time to the ranks of luxury jewelry, did not use the column-wheel (Pillar Wheel / Column Wheel) design, but to use a cheap cam (Cam) of ETA7750, is emerging out of its inherent shortcomings of limited grade . And, because they have introduced nearly 40 years, although the reliability has been widely recognized and praised, but its technical level has been the standard with the times further away.
Now I realize that an outsider can this problem, the Swatch Group already begun to take measures of the natural. As a result, the momentum associated with the upgrade Longines, Longines group seems to be specially prepared for the new generation of ETA movements impressively debut. Since movement is the ETA group brand, will naturally output to other brands, but they have a high quality version ready for the Longines, with L being again named a certain way. In addition, they have one thing in common, that is basically to ETA7750 drawing as the basis the results of modern re-design. Even the sweep movement, too - for ease of understanding, they could be seen as a function of time after the abolition of the redesigned ETA7750. At least, ETA himself says. Well, since ETA7750 is the starting point, then the movement than the sweep, the new generation of chronograph movement can be regarded as "own path." They are ETA A07.231 and ETA A08.231. A07 seems to be in the code Longines L696, while the A08 is called L688.2. Compared to basic movement, polished and chamfered on the more thorough the second construction. Moreover, according heard, in essence, the second construction is not in the Longines Head, but by ETA factory in the factory standard under Longines processing. I think that the Swatch Group, the high efficiency of internal unity, and there is nothing bad.

L696 (based on ETA A07.231) main Spec as follows: the vibration frequency 28800 7.9mm diameter, 36.6mm thickness can be stored automatically on the chain number 27 stone 46 hours timing cam (Cam) L688.2 (based on ETA A08.231) main Spec as follows: the vibration frequency 28800 30mm diameter 7.9mm thick can be stored automatically on the chain 54 hours the number of stone column-wheel chronograph 27 (Column Wheel) now these two chronograph movement, belong to called "valgranges" new generation series, but different from other valgranges, they have yet to appear in the ETA's official website, and not in addition to outside manufacturer Longines get them. In particular, ETA A08.231, rumors that at least within a few years, will serve as L688.2, to become the exclusive Longines movement. As the title of this post described here will only address the L688.2. In short, L688.2 biggest selling point is the blue steel column-wheel. This is it different from the parent ETA7750 maximum points. Column-wheel chronograph not only start and stop the operation more quickly, answering feel better, but also the power to convey decay, etc, and even open the timing function, the impact of travel time is relatively small. In addition, generally inherited from ETA7750 reliable design, landscaping and better polished and more in-depth parts chamfering, making the sound and cutting-edge can be balanced. From design and technology, said to, ETA A08.231 ETA7750 true successor, it will no doubt become a new milestone. ETA7750 successfully as popular as chronograph movement, ETA A08.231 column-wheel design will enhance the basic movement for the future timing Spec. Not only that, and other members of a valgranges, it will vigorously promote the Longines brand promotion.
