I know it seems funny but Bulova made a number of winding and automatic movement "Accutrons" - "Accutron" is just a model line name. Some consumers liked the styling of particular models, but didn't like/trust the early tuning fork movements, so some were made available as mechanicals. The ad is possibly quite correct. The stem at 5 o'clock position is what they should have mentioned.
Reminds me of the re-released Hamilton Ventura...almost everyone went for the quartz movements. Few seem to even realize they were made in a self-winder too. That's the one I got.
