Domestic movement - Hangzhou machine heart 7000 series
The movement of the watch has always been the core of the mechanical watch, the quality of the heart is equivalent to the use of mechanical watches. Hangzhou Jixin 7000 series is a long-powered high-vibration automatic mechanical watch movement. Hangzhou Watch Co., Ltd. has completely independent intellectual property rights.
The movement has a diameter of 30 mm and a thickness of 5.23 mm. The single-box, 28800 repetitions per hour oscillating frequency achieves more precise travel time. After full string, the watch movement can be continuously operated for more than 80 hours.
The structure layout design of the movement is unique. The balance wheel, the pallet fork, the escape wheel, the second wheel and the barrel wheel are in the Y axis, and the bridge symmetrical pendulum plate is more suitable for personalized hollow decoration processing;
After testing, the movement has the excellent isochronism and position difference of the commodity movement, and the difference of T24 hour swing. The quality of the factory trip has reached the industry standard of China QB/T1249-2013 "Mechanical Watch".
The movement can completely solve the practical problem that the commonly used automatic mechanical watch stops when it is not worn on weekends;
The original driving force of the movement is fully utilized, which is the perfect combination of high vibration frequency, high efficiency and low energy consumption. The machine is made of metal parts except jewel bearings, which demonstrates the modern environmental protection concept;
Summarize the advantages of the movement, Lao Deng summarized as: 1, long standby; 2, high vibration frequency; 3, strong stability
1, long standby
In our usual watch movements, whether it is an automatic movement or a manual movement, the power savings is generally about 40 hours. The continuous movement time of the new 7000 model of the Hangzhou watch is more than 80 hours. This means that even if you don't wear it, you can still maintain the movement of your watch when you go to work. As an automatic movement, achieving such a long power savings is undoubtedly improved in practicality.
2, high vibration frequency
For the mechanical watch, the vibration of the balance wheel is operated by the balance. The vibration frequency of the movement balance of the 7000 model series is 28800 rpm, which means 8 times per second, which means that the timing accuracy of the mechanical watch can be higher. . But be aware that such a long power savings also has such a high frequency, which is very rare. The simple analogy: "There is a 3.0T high-performance engine, but the fuel consumption is equivalent to a motorcycle."
3, strong stability
No matter how good the other aspects of the movement, the error of the movement is the key core part. In order to verify that the stability of the movement is reliable, the data given by Hang Table is calculated according to the rules of T24, and the result is the state after the movement of the movement 24 hours, rather than the optimal state of the movement, so The results obtained are more objective and realistic. It also lists the comparison data of a certain movement in Switzerland. Here we mainly talk about the state of the 7000 movement data: the average time difference 7.3 average swing difference is 26.9.
