The serial number of the watch you're looking at is 522037 by the look of it. It fits in with some of the background information on the Internet http://www.thehourlounge.com/index.php?module=Thread&action=view&threadid=9796&id=9796 There's also a good review article, if you haven't alrea
the 222 ran from the late 521xxx to 522xxx, a total of 500 watches - which matches the number at the bottom of the case in that photo. So it looks plausible to me.
