I've had the pleasure of meeting Monseiur Ferrier, Monseiur Muller and the timepiece in white gold with the black dial.
Those who know my watch collecting tastes will know that I am not a tremendous fan of tourbillons, and I like my tourbillons completely covered and discreet (a la Patek Philippe). However, when I saw this tourbillon, I was very impressed about the design of the movement especially with the discreet double hairspring concept.
Anyways, this is my favorite tourbillon. Period. And I am incredibly happy for you that we have individuals here on PuristSPro who are able to appreciate this tourbillon and I am ecstatic that we now have someone who has acquired one too!
