You posted the above quite some time ago and it appears you moved on to German quite some time ago as well, but others may have this same question, so I'm going to take the time to try to add to any knowledge you may have already acquired on this subject. I must confess that although I have a good understanding of the differences between both "watch" and "see," as well as its sister "look," and am certain I use them correctly in English since I am a native speaker, your question made me wonder, what, exactly, is the difference. A number of web pages attempt to explain the differences, but one of the best ones I found comes from www.dictionary.com. I've pasted it below:
Watch, look, see imply being aware of things around one by perceiving them through the eyes. To watch is to be a spectator, to look on or observe, or to fix the attention upon during passage of time: to watch while a procession passes. To look is to direct the gaze with the intention of seeing, to use the eyesight with attention: to look for violets in the spring; to look at articles displayed for sale. To see is to perceive with the eyes, to obtain a visual impression, with or without fixing the attention: animals able to see in the dark.
Hope that helps.
I believe it is the same as it English, as in you can't say that you're "seeing television" to mean that you're watching television. Likewise, in Spanish, I would assume that you can only use "mirar" or perhaps "observar" to say that you're looking at, observing, or watching something, and you can only use "ver" to say that you see something.
Yes, all of them. But it's important to say that "veis" is only used on Spain, not on the other spanish speaking countries.
The translations are:
We see = Nosotros vemos / They see = Ellos ven / I see = Yo veo / He see = Él ve / You (singular) see = Vos ves = usted ve = Tú ves / You (plural) see = ustedes ven = Vosotros veis (just in spain)
To be precise (though this may not apply to all dialects of Spanish), V and B are pronounced as B at the beginnings of words, and in the middle/end of words, similar to a V (the exact sound can be made by narrowing the lips while making a W sound until it starts to sound like a cross between a V and a B).
