Omega seamaster 1975 day & date - Fake or not ?

Hello,

I need advices and authenticity check on an Omega Seamaster 1020 Day & Date.

This one has been renovated, some pieces of the motor have been replaced + polished + the acrylic glass also changed. The serial number is not present anymore due to these changes.

Is this one an authentic Omega ? I checked the model, it refers to a gold one.

Moreover, the price is fixed around 800€. I compared with other models and it seems for me a little bit high. What do you think ?

Thank you,

Ok thank you. What price should it be ?

This is not a really desirable piece for collectors. I would search for something with a Calibre 55x or 56x from Omega. This Watch is Worth 350€ max, the work done adds little value to this piece.

Oh ok it’s a big difference.
Thanks for your help.
