1. Import the data into the sequence RT
the regression equation is as follows
LS RT c r (- 1)
the estimated coefficient of regression parameter C is a and the coefficient of R (- 1) is B. if the equation verification R is 1, it is the exact solution. If it is not more than 0.9, it is the estimated solution (if it is only the equation solution, it is no solution)

2. The main reasons for the slow movement of mechanical watch are as follows: lack of activity and kinetic energy; The watch is magnetized; The movement oil sludge is dry
generally, the date and time of a watch can't be adjusted from 9:00 p.m. to 3:00 a.m., which is easy to cause problems in the calendar transmission gear system of the watch, so it's the forbidden time for the watch to adjust the date ring this period
if the power energy of the watch is insufficient, the watch will slow down or not go. The automatic mechanical watch needs to be worn normally for about 8 hours a day, and the normal and appropriate amount of exercise kinetic energy is needed to support the travel time. Wearing 8 hours a day can support about 36 hours of travel time
generally, a watch is close to a magnetic field. For example, if it is placed next to an electrical appliance (such as a stereo, refrigerator, computer, etc.) that generates a magnetic field and a magnetic object (such as a magnet or a mobile phone), it will be magnetized, which will affect the watch's speed, inaccuracy or temporary stop. If the watch oil in the watch movement is dry, it will increase the friction resistance between the parts in the watch, causing the watch parts to be damaged and unable to operate normally.

3. What should I do if my watch is flooded

1. If the watch is soaked in water, it can be tightly wrapped with several layers of toilet paper or absorbent flannelette, placed about 15 cm near the 40 Watt lamp bulb, and baked for about 30 minutes to eliminate the moisture in the watch

2. Put it in a rice VAT and bury it deep in the dry rice for a period of time. If it's fast, you can see the obvious effect in one night

3. A kind of granular material called silica gel can be put into a closed container together with the watch that has accumulated water. After a few hours, the watch is taken out, and the water disappears completely

4, blow dry with hair dryer, and then apply a layer of transparent nail polish to avoid any rust.

5. If there is water vapor in the watch, you can put it on your wrist with the cover facing inward and the bottom shell facing outward, and the water vapor can be eliminated in two hours. If there is too much water in the meter, the case must be opened for scrubbing. If you can't handle it yourself, you should send it for repair in time.

4. First of all, the mechanical watch [8th floor, block E1, Oriental Plaza, No.1 East Chang'an Street, Dongcheng District] runs fast because of the relatively large position error of the watch. For example, the precision of the hand surface is different from that of the hand surface, and the vertical lucky error is relatively large. When wearing it, its comprehensive even daily error is relatively increased. The position error is a key indicator of the lucky performance of the watch, Generally, the smaller the change index, the better
secondly, there is a common problem with the speed of a mechanical watch, that is, the secondary outer ring of the hairspring rubs against the outer pile of the hairspring, and it is also displayed on the facade and in motion, especially when the watch has been dropped and touched before, and the hairspring is most likely to get out of condition after the transformation; This sub position depends on the movement. If it is the current ETA type male watch movement, it is easier to show the left or upper position of the watch handle on the wrist. This situation requires adjusting the gap between the secondary outer ring of the hairspring and the outer pile of the hairspring, and there should be a reasonable and safe distance between them.

5. Your friend has a bad idea and dreams of becoming rich overnight. It's just that he doesn't want to do it himself. It's hard for others to persuade him to ask his family not to give him money. After a year or two, if he doesn't have any money, he will come back naturally. It's just a matter of time.

6. It is recommended that you can open the warranty sheet attached to the meter. Under normal circumstances, there will be a service address on the warranty sheet, or you can go to a regular watch Service Center for inspection.
ring the warranty period, you can directly send it to the counter for maintenance.

Shanghai and Beijing all have services. You can call for after-sales service

7. It is suggested that you can open the warranty sheet attached when you purchase the watch. Under normal circumstances, the warranty sheet will have the service address (B # 2606, Huarun building, Qianjiang Road, Hangzhou), or find the address of the regular watch Service Center for inspection and maintenance, and the address of the exclusive store. If there is a professional after-sales service center nearby, it is also OK
