Blueberry GMT

[5512vs5513]

Hi everyone, happy holidays!!

I am looking to get more info in regards to the elusive blueberry gmt. I've seen a few priced in the 25-30k neighborhood in the last year or so, so I've been meaning to find out if there is something rare about this watch aside the bezel? Does it have a different dial or case? Maybe a different movement?

From what I've found online thus far (which is very limited) is that they were made for special retailers only (Tiffany, Cartier, etc) or with Military/Government provenance such as the UAE. But I am more keen on finding out if there is anything else to look at while inspecting a 1675 Blueberry aside an original bezel?

As always thanks in advance, and looking forward to hear your thoughts!
