It's a base1000 dial! Don't let the speedmaster collectors see it or they will go crazy.
On a serious note, it looks good to me. At least it's from a trusted dealer.
The grey/black dial is more uncommon than the white dial. Frankly, I prefer the white dial, but these are nice, too. The degradation of the area around the subdials would also drive me crazy and should be a serious factor in its value.
I think the apperent difference in size is not from the pushers, but from the crown. Because the crown in the OP's post is smaller, it makes the pushers look bigger. IMO, the pushers are the same.
