Help identifying Omega Seamaster with Arabic Numerals 3 Rare?

Hello,
Reaching to knowledgeable Omega gurus.
I have viewed hundreds of photos and cannot find a similar number 3. Tried doing the homework but stuck on this one.
I am not capable of removing the crystal, dial etc. to check for movement number.
This is a family watch and was purchased in Germany somewhere between 1965 and 1969 new. Details are foggy.

I am trying to find the date and year of this Omega. It resembles a 1965 Deville but the dial does not show Deville.
The numerals look like Deville but the number 3 is completely different than I have been able to find.
Please look at the 3 and see what you think.
I have not seen the shape of this 3 anywhere.
Planning on restoring this watch so the info would be helpful for parts.

Thanks again
Mike

Thank you for the reply's , It was bought in Germany end of the 60's. Nothing was done since purchased just worn for 20+ years. Would this have happened by a dealer in the early 60's. The timing doesn't seem to add up somehow.
What year do you all think the watch is?

Sorry, I meant would the dealer have done a re-dial then resold it in the store in 1967 -1968? My Uncle swears he bought it new in 1967-68 but memories fade...
I was just trying to figure out the year.
Thank you for all the help, I now know alot more than I did before.
Looking to change out the crystal, polish, new band and service of course.
