Choosing a project watch

Any opinions on these four?

1.
NEW YORK STANDARD 18SZ POCKET WATCH MINT DIAL FLIP MVMT

2.
1913 Elgin Pocket Watch

3.
c1900 Bartlett WALTHAM 24h 17J railroad pocket watch RR

4.
c1910 Waltham Pocket Watch St Lin, Quebec 15 J

I'm not looking to take the watch back to original condition. But I am
looking for something I can work on and be challenged by as many
necessary repairs as possible.

Thanks all and have a happy new year--ya booze hounds 8^)
