1929 Tissot and Omega formed SSIH. 1983 SSIH and AUSAG formed the Swatch Group. So yes, both are Swatch watches at least. Tissot Automatic Chronograph PRC 200 for example is a rock solid Swiss watch @ 600 Euro. You get 1/20 second precise Chrongraph. Thats it. The more expansive watches have more functions, their Mechanik is more complex. U can add Platin and diamonds, make s Rolex. Tissot is one of THE swiss brands at least, as Omega.
