There was a Chronometre Royale thread started in 2014 by Tick-Talk (and inspired by an earlier Respo post) : http://www.thehourlounge.com/en/vacheron-constantin-discussions/and-some-questions-cr-experts-613996
In this thread, there was a question "6340 (central seconds, cal. 1008BS, straight plain lugs). Did this reference ever come with a minutes track on the dial?"
Well, I've been searching a long time for a CR with heavy cylindrical lugs for awhile, but with no success (Ref. 4838 or Ref. 4907). So two weeks ago I got the Ref. 4661 shown in the post that is listed two below this one.
But now that I got this one, I could consider other Ref. # CRs that use cal. 1008/BS. Voila, this ref. 6340 was at a Geneva watch shop and again our dear leader was kind enough to pick it up and deliver to me in Hong Kong! Ref. 6340 is the opposite of Ref. 4661 in terms of having tiny lugs. The watch almost looks like a disc with no lugs, and that is exactly why I got it. This specfic piece was also serviced by VC in 2014, so its in great running condition.
Now to answer the 2-year old question, the Ref. 6340 DOES HAVE versions with dials thar include a minute track on the dial!
