Big Block dial question

[cdog]

I've been doing a bit of research on the Tudor Big Block, and have come across a dial described as an albino panda, with the sub-dials being white on the silver dial rather than black, as apparently was the more common variation. In some pictures of this dial that I've seen, it also appears that the tip of the chrono hand is white, rather than being the same black color of the hand on the standard panda dials. Just curious as to how rare is the dial in comparison to the more common variations. Thank you.
