In the world of mechanical watches, there are three directions are the major brands love and hate, one is complex, one is fine, there is a thin, we love to do any one can cause a sensation, hate Is too demanding, the technology is not mature, high cost. Complex watch currently take the championship should be Farnandr's AETERNITAS watch (see the reading: dark time terminator, Fermolan 8888 GSW T CCR QPS NR), fine watch champion should be respect (this is currently a different, generally agreed Is the respect for the high-pressure, such as several independent watchmaker brand), the thinnest watch is the Earl's Altiplano 900P. Do not say the most complex and the uk replica watches most sophisticated, today that the thinnest, like the watch people know that thin for the mechanical watch is very risky, due to their own structure and component size restrictions, the thinner movement The need to sacrifice the more practical performance, failure rate will be greatly increased. In this year's SIHH, to celebrate the 140th anniversary of the brand, the Earl released the thickness of only 3.65 mm Altiplano 900P, become the world's thinnest watch. Ultra-thin is the most important category Piaget, but also the brand has been constantly overcome the direction of the past 50 years, the brand developed a total of 35 movement, which accounted for 23 ultra-thin movement, is currently all the watch brands have Most ultra-thin movement of the brand. In history, has been to explore the thinnest extreme, in addition to the count, the main Patek Philippe, Audemars Piguet, Vacheron Constantin, Jaeger-LeCoultre, FP movement factory and Lemenia movement plant, but also because there are several replica watches giants lead the way Of the ultra-thin technology is more likely to succeed. Altiplano 900P watch size of 38 mm * 3.65 mm, to achieve its so thin, mainly in the following aspects: First, cut part of the gear thickness, in most classic ultra-thin movement, the gear thickness of 0.2 mm, and 900P The movement will be part of the gear cut to 0.12 mm, thus the release of space; Second, the case directly as the movement of the main splint, the movement of the structure up and down (Glashütty is not the only movement with creative brand Oh), save the The former movement of the bottom of the plywood, easier to reduce the thickness; again, the use of suspended barrel, the traditional movement of the barrel fixed to the motherboard, and ultra-thin movement is often fixed on the winding plate, so easy and The bottom gear is directly docked and eliminates the need for a fixed space; finally, when the eccentricity is selected, the display is reduced, thereby reducing the unnecessary gear transmission process. Ultra-thin watch to achieve, the uk replica watches most important is the support of ultra-thin movement. In 1907, Jaeger-LeCoultre developed a section called the ultra-thin hand chain movement, the thickness of only 1.38 mm, 1960 discontinued, produced a total of 400, was the thinnest movement. In 1957, the count launched 9P hand chain movement, thickness of 2 mm, a sensation. Three years later, in 1960, the count again launched the 12P self-winding movement, the thickness of 2.3 mm, becoming the world's thinnest self-winding movement, it is worth mentioning that it carries 236 parts, more than any one super Thin movement. After that, Jaeger-LeCoultre, Audemars Piguet, Vacheron Constantin jointly designed a super-thin movement, that is Audemars Piguet 2003 and Vacheron Constantin's 1003, thickness of 1.6 mm, until 1994, Jaeger-LeCoultre its improved, introduced 849 Movement, the thickness of only 1.85 mm. In the same year, the count to celebrate the 120th anniversary of the brand, launched a carved version of 9P movement. In fact, shortly after the 9P launch, the brand launched an improved version of the 9P2, the thickness of 2.15 mm, an increase of 0.15 mm, in order to make it more swatch. At present, the Earl's 23 ultra-thin movements have been in production, including the most widely produced 430P (2.1mm), with its blueprint for the ultra-thin self-winding tourbillon 600P (3.5mm), and Ultra - thin self - winding movement 1208P. This year, the brand to commemorate the 9P movement, in particular, launched 900P hand chain movement, I believe in the future auction market, there will be a good performance. On the road to explore the thinnest movement, Lemania watch factory in the last century 80's launched the world's thinnest movement, the chain 1210 movement (1.2 mm) and self-winding 2010 movement (2.08 mm ), Due to the higher failure rate, after the shutdown, the count had also borrowed, respectively, 20P and 25P, but finally did not escape the results of the next frame. 1957 for the count is a watershed, 9P watch in 1957 before the square watch majority, after 1957, 9P ultra-thin watch renamed the current Altiplano, to circular watch, and thus to the classic road. Today, Altiplano Pi Pi watch to become the most subtle series, low-key sense of luxury unspeakable, 900P to join, so that Altiplano on the ultra-thin features once again icing on the cake, become the most popular one of the SIHH models.
