Hi Tom
Welcome to the forum and congratulations, that's really cool stuff, well done!
This bundle is really nice and exclusive, like you said, it's difficult to
find any information about it. I guess, to get it, you have to know about it
and inquire at an IWC-Boutique and then you might be lucky or not.
I've noticed, that IWC Japan made a post with this set on Instagram and I
asked a
question via comment. Shortly after, the answer came via direct message and
they said, that
headquarters told them to remove the post. So, it really seems that there's no
info through official IWC-channels. I don't know why, but this makes the set
and especially the stopwatch really special. Congratulations once more!
