Yes, we have seen at least three samples of the Carrera Reference 2447 T (Tachymeter scale on the dial) in the relatively early polygonal back (or some call it a "hex back"). These three samples represent a fairly large portion of all the polygonal cases that we have seen. I am guessing that the serial number will be in the 56xxx to 57xxx range.

Please let us know if you bring this one home.
