Omega Geneve 131.021

Hi everyone,


I recently bought an omega geneve 1968 - according to my reading of the serial number.

The dial lacking any swiss print under 6 oclock, as well as the crystal also lacking the logo in the center.

1-My question is, is it possible that the dial simply never came with the swiss print?

2- Since it's probably an aftermarket crystal, is it possible that the new logo is somewhere hidden under the tension ring?

I bought this watch for 900 cad $.



Thanks for your advice on above!
