Hey guys...I am brand new to watches and was just looking on ebay for a few movements to practice taking apart and putting together. Can you all take a look at these and let me know if they would be worth getting for this purpose? http://www.ebay.com/itm/311339037472?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT   Thanks!
