So is it correct that the so-called "Grail" Speedmaster is full of plastic parts?

I see conflicting references about whether the movement in this one is a Lemania 5100 or an Omega variant, but I am curious. This is certainly one of the more coveted Speedmasters. I have not followed the market for these in a long while, but five years ago these were fetching twice the price of a 321 Speedmaster and three or four times the price of an 861 Speedmaster.

Somewhat ironic that the collector's grail has this dodgy movement (unless perhaps it is an Omega variation, that has incorporated more metal and less plastic).
