Wang Xiangming | I was learning watch technology experience

I was still in junior secondary school in 1970, but I was recruited in that summer, when almost the entire class (except those born in the "Black Five Class") was basically allocated to factories and commercial units . I was assigned to the Beijing department store, but also engage in watch inspection work, and most of my classmates are warehouse keeper, I am really lucky. Remembered this reason lies in my personal resume "with or without personal hobby column add a few words love hobby, it seems a hobby has a big role.

After two years of workout, you can finally enter the inspection shop to do a dry watch test. The workshop has a huge, noisy air conditioner window. You also need to put on a white lab coat for slippers and put on a white hat. Workshop health is good, the walls are painted azure paint. At that time, the watch inspection is divided into appearance inspection and movement inspection. There are hundreds of watches that make appearance inspection every day. The appearance of the watch is to be inspected one by one. The movement is inspected by 2% sampling. At the time of import watches are all the first table, without a strap, every 10 installed in a paper box inside the watch are set a small plastic bag.

At that time all the imported watches trademark logo, certification, Observatory certification, etc., almost all foreign things are like garbage was drained, according to the old workers agreed: This is because "we can not give capitalist countries Do advocacy ", people of that era talk shouting slogans, especially sonorous! Remember that time the Swiss watch packaging is very good, the outermost is a very thick wooden box, there is a layer of zinc skin and welding seal, and then Is a thick layer of sponge wrapped watch box. Also with a share of special taste, in my memory that is the taste of the Swiss watch it!

When I first entered the laboratory, my teacher did not teach me how to do some work in the workshop all day, and later I bought an old alarm clock from the commissioning bank. I was able to dismantle nothing and gave me some time to toss , One day whim, why the clock can not have two balance wheel it? Try two wheels to try it out; so immediately start the escapement fork welded another fork, the clock plywood A pillar to remove the balance wheel support, but also by the speed of the folder installed it. After a pass, the two balances finally walked up, but it was not long before the rotation of the two balance wheels was not synchronized, and the power spring was insufficient. Later, he was later discovered by the teacher and was accused of being a nonsense! He said that in the world never had two timepieces put in place. Under the severe criticism and education of the teacher, I tried to reinstall two sets of clockwork.

But now there are two or three groups of tourbillon watches came out, the human wonders and the pursuit of continuous efforts will always be the driving force for scientific and technological development. Later in the study, each of our apprentice got a 5-type movement of Beijing Watch Factory, and practiced the technique. A month later, my movement was scarred. I heard that the inclination of the wheel rim was for Put the quality as much as possible on the outside of the balance wheel so that the rotation is more stable, so I use the knife to give the wheel flange an even larger angle of inclination and engraved my own name on the splint. The matter gave me trouble again. It was said by the teacher that it was sabotaging and not cherishing public property. At that time, one hour before going to work, "reading every day" was called "early petition," and there was endless "fighting Private criticism, "and all my things have been criticized for being" self-defeating ". Under the critical criticism and education of the old workers on the platform, they finally realized that they were" wrong "and would never dare to come back.

In fact, the clock is a theoretical work under the guidance of the experiment, of course not chaos, but bold and careful experimental spirit is necessary, you need to observe and record, continue to accumulate their expertise, the domestic watch maintenance staff Most of the tips should be fine, and some may be world class. But I do not think that what is lacking is the theoretical knowledge of watches and the spirit of research. The skills in the hands are never worthy of complacency and bragging, as advanced tools and equipment devalue them.
