I'm not an expert, but I do own a 1133G.
From the available photos, this looks like a very nice, almost mint, example of a 1133B.
BUT, the seller has poor feedback, PLUS the seller and watch not even located in the same country, PLUS no photo of movement or entire dial, so....
...overall, I think this is a big risk.
My 2 cents.
