Unusual IWC (70s?) presentation box

So I received this in the post today.
Anyone seen anything like it?
Dark brown suede-like material on the outside.
Im guessing the age is the 70s-80s...

Cheers,
Adam.

That's very nice indeed!!
Something that will certainly enhance your collection

Hebe is a specialist on IWC boxes.
As a forum member,he will probably react.
I have not seen this model during 20 years.
Kind regards,

This one is blue. 49cm X 27cm X 5 cm

Thanks guys. Its surprisingly good condition considering the material.

Clepsydra - that looks great! Mine looks to be smaller (around 20x25cm) with different clips/locks. Do you know the approx date of yours?

@Adrian: I have just spotted the box, but no details about it ?!

@CAFERACER: Probably an event gift, or a presentation box for dealers.

The content fits perfect, congrats on those watches and that special box.

This one is golden.

Seems to be an good topic, so many fantastic watches in very short term :-)

It's like a box of chocolates, you never know what you're gonna get. :-)

Wow, all quite beautiful. Great boxes there, chocolates and all!
