It's a pretty sure probability that the actual movements in all of the watches that you listed are either exactly the same or so similar that the difference is negligible. I used to work in a building here in Chicago that housed a high concentration of jewelers and had a lot of conversations with them. It became clear that, in their eyes, there were so very few differences in the quality of recently made movements (versus the good old stuff that they saw only once in a while) that it was all the cosmetics of the watch and not the works. Bear in mind that this was about twenty odd years ago and a little bit before the time that China became a major player in stuff like this so the "dynamics" may have changed somewhat.

There have been a couple of pocket watch threads before and the opinions ranged from fanatical devotion to very fine, very expensive timepieces to arguments that economy and disposability are actually a virtue in this regard.

I side with the economy and disposability camp. Having spoken to so many of those watchmakers, I've heard them express the opinion that it was generally more cost effective to completely swap out a broken movement for a new one rather than repair an old one. To me, this makes the value of owning a "fine timepiece" rather dubious...I'm happy to just have a watch that runs dependably and keeps time to within a couple of seconds a month and getting something fixed is usually more costly than it's worth.

Not to say that an inexpensive watch is going to be disposable. I've heard plenty of stories from Old Timers, including my own father, about the "cheap" watch that they bought that outlasted and outperformed the expensive "good" watch that they bought thinking that it was going to be durable and precise.

Thus, I say that all three of those alternatives look acceptable. I'd just look into the warrantee/return policy aspect of the transaction...figger that anything that is going to go wrong will go wrong within the first year. Personally, I like the looks of that one from Amazon...really classic.
