Yes, a watch or a compass, or a cell-phone would have to be hermetically sealed very well in order to survive everyday pressure changes such as aircraft flight, weather pressure cycles and so on.
A well-designed mechanism may incorporate a small air bladder to absorb these changes, but no simple apparatus will do so.
When the air enters the device, due to pressure changes say, it will carry with it some water vapour, and regrettably, this will condense into liquid water when some part of the device gets cool. And it is not simple for this water to evaporate again.
An old watch without its glass face is dangerous because it exposes the delicate internal components to dust, debris, and moisture, which can damage the mechanism. Additionally, without the protection of the glass face, the watch's hands and movement are more susceptible to being knocked out of alignment or getting damaged.
The inside components of a watch are typically called the movement or the caliber. It includes the mechanism that drives the hands and any additional functions of the watch.
The hands on a watch move due to mechanical energy, which is transferred from the spring inside the watch. This mechanical energy drives the gears and hands of the watch to move in a coordinated manner to track the passage of time.
To remove the back of a pocket watch, you typically need a case wrench or a watchmaker's knife to pry it open. Be careful not to damage the watch case or the movement inside when attempting to remove the back. If you are unsure, it is best to seek the help of a professional watchmaker.
Yes, it is recommended to wind a mechanical watch periodically, even when not in use, to ensure that the lubricants inside the movement do not dry out and to keep the watch running accurately. Wind the watch at least once a month to keep it in good working condition.

Additionally, without the protection of the glass face, the watch's hands and movement are more susceptible to being knocked out of alignment or getting damaged.
To get moisture out of a watch, place it in a bowl of uncooked rice or silica gel packets for 24-48 hours. The rice or silica gel will help absorb the moisture from the watch. Avoid using a hairdryer, as the heat can damage the watch.
Since it is an issue of getting moisture out of the tightly inclosed watch face/gears, I would take a modern cue from the wet iPhone and seal it in a container of rice. Rice very readily absorbs water, and will actually leach the liquid out from inside the watch. This is why some people keep rice in salt shakers, to prevent moisture and clumping of the salt.

Do not use this site because it is a horrible virus
You may watch youtube tutorials, or you can watch many movies that involves many swordsmanship in it.
Well the entire point of the movie is to scare you so I guess there is no way to watch it otherwise.
look at it and watch what it does without getting hurt from the living dinosaurs
You go to http://hockeywebcasts.com/
You take it to a watch repair shop, or sent it back to the maker.
You can't
