Can you tell if it is authentic: About to buy 68278

Hello,

I posted on the wrong community, but I think this maybe a better place to post.

This could be her first Rolex. When calling the dealer, they are not telling me whole lot of information. Here is the picture, can you tell if it is authentic?

From what I was told, this is a mid 80s model, with a 92xxxxx (no leading letter, 9 million) serial number. Mid-size 31mm, the picture is from the actual watch, the watch has been acquired through a trade deal, and has been fully cleaned and serviced.

If any of the above sounds in-consistent, I would appreciate your opinion.
Thank you,
Jim
