Please note, this is in Gaming Scale, not 54mm. There will be raised hand variants with this piece as well. Per George on his "Not a BLOG" (as he leaked this sculpt early):
"Purists should take special note of the maester's chain about Luwin's neck. Tom's is the most accurate visualization of the chain-of-many-metals I have seen to date. This is how I have always pictured these chains, and how I described them in my books. (though I should mention that Pycelle's chain is much grander, larger, and more ostentatious, him being the GRAND Maester and all)."
