There are two different meaning of the word 'wind'. One can be like the wind in the air, but the other can be as in 'to wind up a torch' or annoying someone. Here are three sentences for each: "The wind carries tiny things because it is powerful." "The wind is very strong today so be careful your paper doesn't blow away." "The wind annoys me because it messes up my hair." "James likes to wind up his brother." (James likes to annoy his brother.) "I have to wind my torch up every five minutes." "Wind down the window so that I can speak to that other driver."
all windup watches work by a mainspring that is wound up really tight, the spring wants to let go as soon as it is wound up tight. as you wind up the mainspring that parts in the watch start to move and the watch starts to keeps time. this is called a balance action. the balance wheel has a hairspring under it that returns the balance wheel to its main position as you wind the mainspring the force of it puts tension on the parts and that is how the windup watch works.
It provides the light in the torch
Are you serious????
The wind can blow in any direction.
