...AP has an in-house manual wind calibre except cal. 2936 - tourbillon chrono for their RO-which cud easily be modified with regular escapement but thats just a guess with sz. They now have at least 3 automatic calibres for chrono I believe.
...I want to really love the Remaster, but it is far too thick. The look is perfect, but it needs to have a manual-wind movement to get my $$. Maybe next year...
