in the 2000's with a series in platinum, but with the advent of XGT cases and the Antoine LeCoultre in platinum, it was never completed.
The Reverso Platinum Number One (skeleton), in 2001, the Reverso Platinum Number Two (tourbillon w/power reserve) in 2003, were the only 2 pieces "officially" part of the series. A 2nd Skeleton (highlighted in the book "The Grande Maison") COULD HAVE continued the series, but the public was already onto the larger case and the benefits it offered.
With the Septentieme came the new, XGT case, and a bunch of GREAT complications came as a result of it. Personally, I REALLY like the 8-day power reserve, and would love to see it in a slimmer case (though I have NO HESITATION) wearing the Grande GMT, which is a personal favorite. However, a thin 8-day with minor complication (pointer date?) might be nice.
