Listen to me, Sir.
I never ecountered a rep box which would pass for a genuine one.
For example, my last acquisition was a 1:1 (supposedly) Blancpain rep box from Trusty Time.
Andrew was a great great guy; excellent packaging and fast shipping...but the quality isnt even comparable to the gen box
...
How do i know ? I own a genuine Blancpain box....and the wood and finishes are light years apart...
So, in the end...i suggest you tu buy a gen used box on ebay or catawiki !
