Thank you Teeveetee, the engineering of a mechanical watch fascinates me. I would love to one day make it to Schaffhausen and take a tour of the IWC factory.
On a side note, I was going through old boxes in my parent's house a few weeks ago and came across some of my father's old watches (none were IWC, but there were some very interesting pieces), and after winding them, without hesitation, they ran perfectly. I am going to have them serviced to clean up the movement when time permits. I can only imagine what it looks like inside after having oil sit in place for at least 30-40 years. Come to think of it, I would probably have been better off not starting the movement!
It amazes me where technology has taken us, but there is something about having an mechanical watch that is so special.
