I have never stated that IWC somehow hides that they use ETA movements or add on modules, so I'm not quite sure why you chose to tell me that. But thanks anyway. ;-)
In any case, as John has pointed out (I was hoping he would jump in on this discussion) some of the quotes don't make a lot of sense. The first set seems to provide a lot of detail, but then it reverts back to being somewhat vague, at least to me. For example this statement:
"The entire escapement is a good example. It is ordered separately with different, more exact technical IWC specifications and is only fitted into the calibre at the end of the assembly."
Underline mine above. So they replace it with another escapement, but that is apparently also an "ordered in" component, so who is it ordered from? ETA?
Now the second quote you gave contradicts the first:
"Nearly all critical components along the path from the escapement to the mainspring are removed from the movement and replaced with corresponding components from IWC's own manufacture. "
So again to me it isn't clear what is really done. And BTW I have a friend that is a jeweler than can "upgrade" your ETA with gold plating for about $10. ;-)
Thanks for the discussion.
Cheers, Al
