You could get a 933888 for 100 euros but the font is smaller on the ETA from B65 cal and forward. I have a gen Cal 75 and it is also a termocompasated movement loses about 0.5 seconds per year, great watch!!!
100% Genuine here to compare, in the Gens there is also a tiny tiny gap between the Dial and slide rule because of course they cannot touch, only visible from a side zoomed pic.
At last, a side pic to see how the Gen slide rule aligns, with the Rep slide rule the Gen Dial was under it because the Rep Dials have a smaller Diameter.
