need a watchmaker?

Hi everybody, I'm an italian watchmaker who wants to live and work in Canada, but it seems pretty difficult to me to find job in my field. Does anyone have any advice for me, I'd like to apply as a skilled worker but I really haven't realized yet if it's better to apply for a job while outside Canada and then make a request for immigration to the consulate (with already a job offer), or if I should first file in all the documents to immigrate and apply for a job while in canada (in case I'm choosen). I'm a little confused about it, also because quite all the sites of Canada or Alberta immigration program suggest to apply for a job first, while by the other hand I read that's very difficult or almost impossible finding a job if your're not in Canada, even if you have skilled abilities.
Please help me clarifying this point, thanks in advance to anyone who will help!
