I found a very interesting thread from August 2007 by Adrian, where he explains that there were only two batches of civilian Mk 11s issued, one in 1973 and one in 1983. Are these the only civilian Mk 11s around? According to the thread all these models also had 7 digit serial numbers on the inside case back. My question is: do these serial numbers follow the normal numeric system used by IWC on all their (civilian) models, or do these batches have a separate serial system?
Thank you for taking the time. Any answers would be much appreciated.
Cheers,
Jan
