yes it is in fact a modded Swiss 7750 - as Pugwash already mentioned
it performs as you would expect from a Swiss movement (smooth second hand, keeps good time, etc.)
Here is a list of flaws that I am aware of:
hands too thick 5 minute markers are supposed to have the same length and are shorter CG engraving to big tick marks for the seconds are supposed to go from the dial to the bezel the color of the lume is white rather than light green - no luminousity anyway and too bold/thick movement ....pretty much all the engarvings, bridge finishing, blued screws missing or wrong sapphire has no AR coating and is mineral no Flyback function this is actually one of the PAM's with a lot of flaws, compared let's say to a 111, 127, etc. however it is still a beauty
here is pic of the gen fro comparison:
