Hi I have the opportunity to pick up a cal. 8531 IWC Ingenieur (ref. 666 AD ?) and was hoping to get some help. First some pictures of the watch in question:
Now the questions:I have used the date my IWC and accoring to it the movement seems to be from 1963 where as the case (serial 1,840,xxx) is from probably 1967 but between 1966-1970 for sure. Is a difference of ~4 years between the case and the movement normal for an original IWC or is this a sign that the movement has been replaced?
Does anyone know what IWC would charge for a service and new dial? (I have read $900 and $500 respectively but don't know if this is up to date). Is there anyone else who you would trust to service a watch like this?
I'm having trouble coming up with an estimated value as I can't find any sold on ebay. I have seen a number of better condition ones on chrono 24, but (imo) chrono 24 sellers tend to over value their watches. Would averaging those and dividing by 2 give me a realistic value?
If someone could pm me links to some comparable watches sold or other way to estimate the value I'd be grateful.
Any other info and options would be appreciated as well. Thanks in advance.
