There is (was?) an automatic model with 3 functional subdials. Non a great rep (with the usual problem of the excessive distance of the subdials from the center, wrong hands, wrong back inscriptions etc.), but acceptable. The existing hand wind models, instead, have only two functional @3 and @9 subdials (seconds and minutes), while the one @6 is fake and follows the movement of the hour hand (I asked a rep friendly watchmaker to freeze it @12 in my rep Tin Tin in order to make it look slightly more credible).
The lack of a serious Speedy rep led me to buy the real thing (considering that it is fairly affordable, especially in the second hand market.
