Which factory? Can't decide which one is best.. always loved these Annual Calendars.. and I need to add another IWC to the stable (maybe two) if I opt for a nice Ceramic Pilot Chrono..
ZF factory. Just be aware: you are committing to one complex piece
. Somewhere in the IWC thread I posted this movement on the workbench. c.o.m.p.l.e.x....
Setting date is a chore too, which is why it is wrong on the pic. I stripped a gear on the first day of ownership, which required a (free) factory fix via my favorite TD. Also, this blue hands version was never released in gen. But, man, it is a satisfying watch to own.
