I can see the tourbillon model will be a little slower selling due to the higher cost, unusual height, greater amount made, and unconventional layout.
The last two MB&F items I bought both sold out before I got a chance to buy them. For the item one I worked with the M.A.D. Gallery in Geneva; I saw the item in January, decided I wanted it in February and it was already sold out. I was able to procure one when a buyer dropped out and my name was among the first on the waitlist, so I was very very happy! The item two, I didn't get my top choice in color nor second choice, and I had to fly to Singapore to MB&F's retailer L'Atelier by The Hour Glass to complete the transaction. So I've worked with both the MAD Gallery in Geneva and L'Atelier in Singapore and both are fantastic. MB&F really has a great internal retail program with their galleries and an excellent relationship with their retailers.
