Hi Nico-I bought one of these a year ago-it turns out it is not a standard size and not genuine. In my case, a genuine Heuer caseback did not fit and after being assessed by some Heuer experts, we concluded there are other issues with these cases.

I managed to get a refund at the time, despite claims from the seller he had fitted 8 of these cases with other parts!

Good luck,

Steve

Hey guys,

: two weeks ago I found this offer at ebay:
: http://www.ebay.com/itm/HEUER-CARRERA-HANDWIND-1970IES-CASE-WITH-GREY-INNERBEZEL-NEW-OLD-STOCK-/121997867681?hash=item1c67a3baa1:g:uEUAAOSwagdXRuWG

: I just bought the white-tachy-bezel one, cause I just needed the
: bezel for my Poor Man's 73353. Today I got the message, that
: this is not a 73653 case (I sell the rest of the case at CT) but
: for a ordinary Valjoux 7765.

: Can you confirm this isn't Heuer? It misses the SN between the
: lugs, but the rest fits the 73653 in my opinion.
: If this is not legit, I would try to get a refund and of course
: delete my offer at CT.

: Cheers Nico
