Antique Pocket Watch Store

Where can I get gears?
I try to make steampunk jewelry like this: And http://www.craftstylish.com/assets/uploads/posts/50992/clock_gear_pendant_4_lg.jpg I've done it before, but I used old pocket watches, which were pretty banged up, and short of going to an antique shop and buy more pocket watches, I have no idea where to get some gear. Every store is well, I guess even a good reliable store Internet is good too, or even ideas to bring them out of other old machines random (I have more than enough lying around) Anyway Regardless, please help.
I would try Etsy. There is a large community of artists and suppliers steampunk it. I've listed links to some vendors that I used and that often have what you are looking for.
