Well here's another unusual brand to add to that list:
Illinois.
At lunchtime, I ran my usual set of searches on Yahoo Japan, but didn't find anything of interest. I search in both English and Japanese and before I finished I did a random search on 'クロノグラフ' (Chronograph). This came up in the results:

It's fairly obviously a 7T32, from the two crown, three pusher and sub-dial layout with alarm. The Yahoo Japan seller has sussed as much from his translated description. Apart from the
Illinois branding, it's unusual for a couple of other reasons, notably it's smaller than average (only 34mm diameter with 17mm lug width fitting), prominent chronograph pusher buttons @ 10 and 2 o'clock and the Rolex style knurled case-back, which presumably screws down.
Underneath the upper part of blue vinyl case-back protection film, it's possible to make out:
Illinois Watch Co. Ltd.. Back in the late 1800's and early 1900's, the
Illinois Watch Company was a well-known mainstream US manufacturer of pocket watches. Whether this watch is a product of the resurrected
Illinois Watch Company (owned by Craig Stone) or just some Chinese outfit ripping off the brand name while the company was dormant - your guess is as good as mine.
Edit: According to Wikipedia (and the date of trademark acquisition of 2009), I suspect it's more likely the latter.
