Vintage Omega Geneve

Hello,
I recently received a Vintage Omega Geneve 135.070 601 Caliber made roughly in 1970.
Besides a bit of dirt or debris I’m an unsure how genuine it is. The dial could be a replacement.
My main concern is the 6 marker obscuring the Swiss Made font.
Any help would be greatly appreciated!

I would guess that it's been repainted based on the texture of the paint and the mismatched lume on the dial and hands. The text and minute track look fine to me from that photo, though.
Edit - the applied Omega logo looks too old for a model of this time period. I would expect it to be flat instead of rounded. Disclaimer: I'm not at all experienced with this model, so take my observations with a grain of salt.
