Despite the obvious design differences of both the movements, both are duo-winding, that is, they wind in both directions of the rotor. One is made by Felsa, the other by A. Schild. The one by AS is based on a smaller 9 ligne version of the calibre.
I believe the word or designation "Self Winding", is not a model name, as it was used by other companies also, and merely describes the automatic winding nature of the movt. Duo Wind, on the other hand, is/was a model name as well as a Bulova designation. No other companies used this, as you might expect.
