The next day at noon.

Lunch breaks.

Commercial airliner manufacturing company, in a workshop.

"Zheng Gong, light movements in your hands, operate carefully, don't damage the internal structure of the watch, this watch is a gift from my son, don't break it, otherwise I won't be able to explain."

On the side of the console, Chen Gang repeatedly reminded on the side, although this watch is only worth 80 yuan.

"Got it, don't bother me on the side, I'm a national special technician, my subordinates are measured, if you don't worry, go find someone else."

Zheng Gong put down the screwdriver in his hand, looked displeased, and stared at Chen Gang next to him, very annoyed by his crookedness.

He is the oldest and most skilled skilled worker in the landing gear design department, although he has no education and is poor, but in the first-line production workshop, he has more say than anyone else.

Even Xiao Jinsong, the chief designer of the aircraft landing gear, had to politely call "Lao Zheng" when he saw him.

Today, the deputy chief teacher Chen Gang found him and said that he wanted to ask him for a favor and crack a "thing", he felt that Chen Gang was not bad, he was a high-level intellectual, so he was willing to help him with this, but he didn't expect him to have so many fame.

"I'm sorry, I'm sorry, Zheng Gong, you can do it, I won't open my mouth."

Chen Gang hurriedly compensated for it, in fact, his own hands-on ability is not weak, but on the edge of the mechanical watch, he looked at it with a magnifying glass, and there were 8 screws that could not be distinguished by the naked eye that were not much thicker than a hair.

Seeing that Chen Gang closed his mouth, Zheng Gong's face improved a lot, and then he picked up the smallest micro screwdriver and concentrated on opening the mechanical watch in front of him to see its internal structure.

Staring at Zheng Gong's hand movements, Chen Gang next to him held his breath.

With anticipation on his face.

In my heart, I was extremely apprehensive and excited.

The truth...... It will soon be revealed.

He still can't believe that a knock-off watch bought from a stall for 80 yuan, after wearing it on his hand for nearly two months, the time error has always been 0 seconds!

That is, it has always been consistent with standard electronic time.

But it's a mechanical watch!

The use of twist spring accumulation, the congenital error is a large mechanical watch.

For example, the first-class watches of the internationally famous brand Rolex have an error of about ±30 seconds every 24 hours.

The finest Swiss parts are made from a large number of hand-made, hand-adjusted Longines watches by master watchmakers, with an error of less than 2 minutes a month.

But compared with the 80 yuan copycat mechanical watch worn by Chen Gang, the international famous watches on it are all spicy chicken.

Because almost two months after this copycat watch, the time error is 0!

In fact, when Chen Gang wore this copycat watch with accurate timekeeping for two weeks, he felt that something was wrong, but he didn't pay too much attention to it.

A month later, the time display was still so accurate, and he finally noticed the anomaly in this knock-off watch.

The next nearly a month was a process of expanding mysteries and curiosity in his heart, and finally tormenting him to take action.

You must know that as a senior engineer who studies aircraft landing gear, his career can be described by the word "high-precision", and at the same time, the characteristics of this profession make him particularly sensitive to precision, and it is easy to notice some details.

And the time on the watch, he goes to see it every day......

So this month, his spirit has been tortured enough by this 80-yuan copycat watch!

Now, he wants to put an end to this torture and find out the truth about the accuracy of the copycat watch!

Zheng Gong's micro-manipulation ability is really not covered.

About two hours later.

The screws on the edges of the watch are all unscrewed.

The carbon fiber back cover is slowly opened.

The internal movement, gears, balance springs and other structures are presented in front of Chen Gang and others, exuding a silver and metallic luster.

Zheng Gong, who was in charge of the dismantling, was first stunned: "This ...... There are probably tens of thousands of parts in this watch! ”

And many smaller parts can only be seen clearly with the help of industrial microscopes.

In the microscopic field of view, many parts that are invisible to the naked eye are like the internal machines of a large factory, completing their respective tasks.

After observing a special, mysterious device less than the size of a thumb.

Chen Gang, whose eyes were full of shock, found the reason for the accuracy of this copycat mechanical watch.

"Atomic clock, inside this watch, there is an atomic clock embedded to correct errors!"

There is a display screen the size of a grain of rice on the surface of the atomic clock, and a line of numbers displayed on the screen: 9192601770, represents the number of vibrations of cesium atoms in one second, and roughly calculates the time accuracy of this atomic clock, and the time error of more than 100,000 years will not exceed 1 second.

"It can't be!"

Chen Gang shook his head violently: "How can an atomic clock be so tiny, the smallest atomic clock in the world is the size of a jewelry box, and the size is ten times that of this watch, how can it be compressed to this extent?" ”

At this moment, Zheng Gong looked like he was deeply hit.

His hands trembled a little, and he muttered in his mouth: "Is this the real gap between our country Z and foreign countries?" How is it possible to catch up? Is it not enough to fight day and day in the past thirty or forty Chinese New Year's Eve, and we must continue to struggle for 30 years before it is possible to catch up with the most developed science and technology in the West? ”

The problem is that he is already over sixty years old, and there is still so much time to see the day when country Z surpasses the West?

Can only continue to spend time in discouragement?

It turned out that the English on the copycat watch made Zheng Gong think that this watch was the most technologically advanced masterpiece in the West.

At the same time, it also represents a huge technological gap between country Z and the Western powers that cannot catch up in the short term.

He was deeply devastated by this, and a bitter inferiority complex welled up in his heart.

Fortunately, it is working time, everyone else is working, in this workshop, only Chen Gang and Zheng Gong are absent from work, and only the two of them are temporarily hit.

And Chen Gang was less hit, he was more surprised and puzzled.

I was amazed that this watch could be bought at a stall.

It's only 80 yuan......

"Watches are industrialized products, and there is definitely more than one piece in production! Since you can buy one, is it possible to buy a second or third......"

Thinking of the great value of this watch, Chen Gang picked up his mobile phone and made a call.

"I must ask my son about the situation, and I must find the whereabouts of the stall owner!"

……

Inside the Industrial and Commercial Bureau.

After my mother made a phone call in advance, the Industrial and Commercial Bureau really opened a green channel for Chen Jin.

The business license, which originally took about three days to complete, can definitely be won in one day today!

She is a friend of her mother's in the Industrial and Commercial Bureau, surnamed Dong, whose name is Dong Lei, in her forties, and is a middle-aged woman with charm.

And this female leader is very talkative and very enthusiastic.

When guiding Chen Jin to apply for a business license, she asked many questions:

"Xiao Chen, why did you think of opening a jewelry store?"

"Are you really the one who runs the jewelry store? A 300-square-meter store, can you take care of it as a young man who is starting a business for the first time? ”

"Will your family help you?"

Chen Jin gave an answer to these questions, saying that the jewelry store was opened by himself, and the funds were also solved by himself, and he did not ask for a penny from his family, and recruited people to take care of it himself.

Dong Lei nodded.

Through this young man's performance, she firmly believed in the judgment in her head!

He Li's son, is by no means a mother's boy!

It is an aspiring young man with ideas, brains, and courage.

Of course, judging from his academic qualifications, he is not very good, but his polite attitude and methodical speech make her impression of this young man better than those of those highly educated turtles and young and handsome rich children.

Because he does not talk about it, he does not talk about it, he does not shy away from talking about the problems he faces...... It feels very down-to-earth.

Dong Lei likes this young man very much.

But my heart was full of doubts.

"This young man, is it really a mom boy?"

"Did Linlin have some misunderstanding about him?"

"Director He of the Taxation Bureau, how could such a shrewd person teach his son to be like that?"

"I think there must be some misunderstanding here!"

Dong Lei is a person from the past, and knows that in the relationship between men and women, the first impression may not be accurate, and it is very inappropriate to beat someone to death with a stick.

And after she personally inspected it, she felt that this guy was very good and worthy of her daughter Linlin......

So after the business license was completed, he handed the relevant documents to Chen Jin's hand, took out his mobile phone, and said to him enthusiastically: "Xiao Chen, come, add a WeChat, if you encounter any problems in the future, you can ask me at any time, and we can contact him at any time." ”

Chen Jin's face was overjoyed: "Eh~ Thank you, Aunt Dong, on the day my jewelry store opens, I will definitely invite you to dinner!" ”

"What's polite, do a good job, I wish you success in starting a business." Dong Lei said with a smile.

"Then I'll take my leave, Aunt Dong, you go and do your business."

Chen Jin solemnly put the business license in his briefcase and walked out of the industrial and commercial bureau with a happy face.

"Bell bell bell ~"

As soon as I walked to the door, the mobile phone in my pocket suddenly rang.

Dad called.

"Son, can you come to my company, I have a few very important questions for you!"
