The basic structure of the movement of famous watch machinery is not complex. The structure of each movement is the same in essence. However , when realizing various functions, there will be some trivial and even extremely subtle problems. For example , whether the gear meshing is accurate, whether the tip starts smoothly, and if the transmission torque is stable. These small problems will not affect the function of watches, and most brands will not spend too much effort to solve these little problems. However , a few brand names will try their best to solve these subtle mechanical problems, and develop new technology structures for this purpose. This is Patek Philippe Aquanaut 5968A-001 Chronograph. The latest embodiment is the 5470 chronometer. 5470 is the first 1 / 10 second chronograph in Patek Philippe's history, with a swing frequency of 36000 times or hour. 1 / 10 second chronometer is not uncommon in famous watches. Zhenlishi El primero timing movement, baopo F385 timing motion and grand Seiko guanlanshi 9s series movement all have a swing frequency associated with 36000 times / hour and an accuracy of 1 / ten second. But there is a problem. Most of the one / 15 second timepieces are also the central used. They turn once within 60 seconds. Although the movement can reach the actual accuracy of just one / twelve second, we can't see it with our naked eyes. Previously, zhenlishi has been committed to solving this problem. Now, Patek Philippe has also joined the ranks and made a timepiece with 1 and 10 2nd accuracy that can be seen through the face. The sophistication of technology is unmatched. This is 5470.
