The only restriction I foresee is the budget or cost of the watch. I hope it is something most people will be able to afford, but that largely depends on the number and type of mechanical watch we all agree on. Since a lot of people already have the 1963 (in all of its various guises), it would be probably be better and more adventurous to go for something different.
Methinks you are jesting on the tourbillon Michael .....or it will be at most a limited edition 0/0 ......I definitely don't have the moohlah for one of those either!!!!
