I think the number and the ship's design (albeit perhaps with details a bit modernized for contemporary audiences, which might cause some confusion) is intended to show exactly when the series is taking place.
I don't see why Fuller and company would need to release a misleading teaser. They've already disclosed that it's going to be set in the prime universe, which is all you need to get most of the diehards back on board (at least temporarily, lol). The idea of a teaser is to sell you on the show, not pull a bait-and-switch on the entire premise.
