Thinking of my first sitter, what to look for on a budget?

As the title suggests, im looking for a first shutter. I have a few good watches already, but no reps yet. As it is my first purchase I would like to keep the cost low, preferably below $50 (I know, really low). Quartz or automatic doesn't really matter to me, ofcourse auto would be nice, but no must.

I have a few watches I like, so if one of these is possible that would be awesome! Here they are:

- A Rolex Land Dweller

- Omega Speedmaster

- Tissot PRX

If anyone could help me or give me advice and information about all of this that would be awesome!

I have DHgate already, and I have had a look but there are so many that dont have a lot sold or no reviews so its a maze for me lol.
