Lee, with the wide coverage given to the Basel prototypes nowadays, we see copies making it to market long before Heuer itself actually gets round to productionising and selling the watches. It was the case with Monaco V4s (as TH took soooo long to do it themselves) and it was the case again with the LS. These copies don't have the proper functionality (obviously, with something like the V4's belt drive) but can start cropping up on eBay and elsewhere within a couple of months of appearing at Basel, which is impressive in itself, even if the copy often isn't.

I posted about the production version of the LS almost exactly a year ago: http://www.chronocentric.com/forums/heuer/index.cgi?noframes;read=30603

The watch should be the same everywhere around the world, make sure anything you buy looks like the lower of the watches in that post, the copiers have hit the prototype rather than the production version in most cases, though I dare say they've gotten round to that one too by now.
