Due to the world's largest manufacturer of basic movements, the external supply of lower ETA movements has been limited since 2008. Many manufacturers are unable to obtain ETA movements and are looking for their replacements. Just like the automobile Mercedes-Benz, Mercedes-Benz supplied engines to foreign factories in the early years, but now they do not! The automobile factories that had been relying on Mercedes engines to make their products could not survive. You can only find other products. I'm sure many of you who play with watches are familiar with the Shanghai 7750 movement. It has a great reputation in China and Asia. Because it is a versatile movement, it can be described as 10,000 essential oils and is useful in many intricate watches.
The same goes for watches. The more relatively simple it is the more durable it is. Therefore, we also need the correct use of 7750 watch movement. In this way, how should it be scientific and reasonable to fully utilize the Shanghai 7750 watch movement, can scientifically and reasonably improve its use of time? We all mainly in-depth analysis of these several levels:
1. Don't adjust your time from 9pm to 3am. The ideal time for proofreading is from 10am to 2pm.
2. So try not to adopt the basic function of timekeeping of the imitation watch as often as possible, the basic function of timekeeping of ETA can not withstand a long time of work. (Shanghai and ETA's timekeeping basic function are all will affect the error value)
3. Hold it lightly, take good care of your watch, will also cause you good performance.
4. Proofread the calendar and make sure you pull it into gear every week to make adjustments. (so as not to damage the worm gear drive) The lighter and slower the better (you will get the rhythm when you get good at it). The best way to do this is to pull into second gear and drive with the hour hand.
5. Put aside the first time to adopt the upper hair about 5 turns, so try not to wind. Although there is a self-protection working mechanism, customers with slightly heavy hands and feet may cause a lot of unnecessary trouble.
What is the difference between the essence of Shanghai-7750 and Dandong-7750?
1. Dandong 7750 small seconds from 9 o'clock to pull down 6 o'clock 3 worm gears drive in the direction of the geomagnetic field.
2. Previously, Shanghai 7750 turned 1 turn, Shanghai 7750 changed 5 worm gear drive, 5 worm gear drive became stepped.
From all of the above, it can be seen that the Danton 7750 is more durable. An in-depth analysis of the after-sales repair rate at this stage of the period can show that the Danton
The 7750 watch movement is a lot more stable than the Shanghai 7750 watch movement In the final analysis, many unnecessary clipboards and spare parts are changed and removed, which greatly
The extent of the equipment failure rate has been drastically reduced.
