Any chance this Speedmaster is from 1986?

Hi everyone, I've been on the hunt for a decent Speedmaster from 1986. I would have typically looked for the long S/R dial, but then came across this version, which according to the seller, is from 1986 and fully original. I won the auction at a good price, but forgot to check the bezel and then noted that it was from the later versions (dot below 70, dot next to 90, accent over e).
I have an option to cancel the auction, but before I do so, still wanted to check if there aren't exceptions to the rule, and the seller could be right.

Yes, forgot to mention that- I always check serial numbers but given the nature of the site, I could not do that before submitting the bid. I was anticipating that the serial could even be correct, but that I would still end up with a watch with a later bezel.
