The task posed in the title seems straightforward. What is easier: toss the clock into the wall, hit it with a hammer, drive a car over it - and that's it. But there are also more subtle methods. We will consider five such "know-how".
Method number 1. Adjusting calendar indicators at the wrong time
Almost all watch movements with a date display (and day of the week, if there is such an indicator) have a negative attitude to the correction of these data for several hours before midnight and several hours after it. The fact is that, although theoretically the change of the date and day of the week occurs exactly at midnight and, moreover, instantly, in real life of the clockwork it is somewhat different. The corresponding wheels take a certain amount of time to turn and stop in the correct position.
You can observe this on the dial, in the corresponding window of which the previous one, for example, the date begins to "creep" out of the visibility range at about 21:00, gradually giving way to the next one. Finally, this process ends at around 03:00.
Interference with the mechanism, forced "twisting" by rotating the crown, extended to the position intended for this, can simply jam the mechanism. It will probably be possible to repair it, but for decent money. If you don't mind - go for it!
Method number 2. Screwing the crown down anyhow
A screw-down crown is a good thing, of course. The threaded connection, and even properly sealed, significantly increases the tightness of the watch case, which prevents any harmful from getting inside - moisture, dust, dirt. However, for some actions with the clock - for example, for the aforementioned adjustment of the calendar - such a crown must first be unscrewed. Not completely, but nevertheless! And then screw it back.
This is where there is a subtle point: if you press it crookedly, the head may not go along the thread. You could stop, unscrew it back, so that you can repeat the process more accurately ... But brave courage is still breaking out! This means - forward, spinning with all our strength, overcoming tangible resistance! As they say, if you don't want to - we will force you!
As a result, what happens in technology is called thread stripping. It is unlikely that it will be possible to cut it again. Congratulations, you have won, the body is damaged "by five points."
Method number 3. We start and stop the chronograph right under water
This may sound dubious: many diving watches are equipped with a chronograph function. Correctly, equipped, and this helps to control the stay in the depths of the sea. However, if there is a desire to experiment, then let's, already immersed, press the buttons of the chronograph. Stop-start-stop ... So he stopped, hurray!
Because in the course of this game, the same tightness of the case is inevitably violated, water penetrates inside - well, then it's clear, right? If the water is also sea water, then it is absolutely great: salt will damage the mechanism in a particularly sophisticated way. Yes, so as not to forget: if the chronograph buttons are screwed down, do not forget to unscrew them directly under water, otherwise they will not press down ... Well, then you will have to fork out for serious repairs, or even for a new chronograph. Are you ready for this? Then go ahead!
Method number 4. Push buttons without fanaticism
For example, perpetual calendar buttons in a number of expensive models. They, these buttons, are designed to adjust the readings, and they themselves are small, not protruding from the body. Press them, as a rule, with a special stylus. And they press to the end, which is indicated by a click. But is it worth it to balk?
What is there "to the end", and so it will work! And, remember, we have a different task - to break! So we press these buttons with lordly negligence. It will jam almost inevitably. For example, the date will "get stuck" between the 7th and 8th. Or the moon phase will go into a stupor. Etc. Nice breakage way, exquisite.
Method number 5. Playing with magnetic fields
This is especially true for small children. True, it’s so interesting when a magnet attracts all kinds of carnations and other small things ... And the clock? And even more interesting! And if we are not small children, but quite adult gentlemen? Calmly, in every man there is a boy, this is well known. In addition, he is burdened with more complete knowledge - for example, about fields not just magnetic, but electromagnetic.
Let's put it bluntly: in domestic conditions you will hardly be able to find such strong fields to move the clock even by a micron. It's a pity, yes ... But magnetizing the main regulator of the clockwork - the balance / spiral assembly - is very possible! There are, of course, watches that are protected from such games - with silicon components of the movement, with an inner capsule made of soft iron, etc. But not all clocks are like that. If you are lucky, they will begin to walk completely wrong, and you have to go to the watchmaker's shop. But knowledge is power!
