So proof positive that I have been living a somewhat un-examined life - apparently when Bell & Ross has utilized the letter X in its naming conventions, it is to indicate that the watch is part of an experimental range.  Clearly I've been a bit asleep at the switch.

Having said all of that, this is the BR-X2 Tourbillon Micro-Rotor.
