If you're interested in the hobby of vintage watch collecting, Timex watches are a great place to start learning. They are inexpensive to purchase (and therefore, rarely faked) and easy to find.
But, as with many hobbies, you should read up on the hobby before you jump in. Most vintage watch collectors strive to find watches that have not been altered since they left the factory 30, 40, 50 years ago. Although this forum is called "Omega Forums," there are many threads written by experienced collectors that coach beginners on what to look for in a vintage watch (of any brand) and what to avoid.
Start with these threads:
