Omega Constellation Authenticity

Hello,

I received this watch on donation, and would like to know what everyone thinks of it before I attempt to sell it for charity. I've found some information regarding date, model, etc. based on serial, model numbers.

I have no background information on the watch, and little knowledge about it to go with. It's not my watch, so if there is any doubt of authenticity, I won't be offended/bothered.

I am curious about the text spacing under "Omega," and the crown. I am also asking if the case, movement, dial, and/or hands are matching.

Thank you for your time!

Thank you

Was going to mention the crown as replacement

Appreciate it, thanks

Will do, thanks - wanted to see what you guys thought.
