Like any watch seller / dealer I would be wary of even Hodinkees depth of knowledge of every brand they are selling. Point to note is this one http://shop.hodinkee.com/collections/watches/products/1960s-wittnauer-professional-chronograph-reference-6002-5 the bracelet is on my opinion not original to the watch, the end links are not the same and from my experience of owning a one I would say the bracelet is from a 7004A https://heuerville.wordpress.com/2014/05/21/wittnauer-ref-7004a-chronograph/ which featured slimmer lugs. Just saying...
