Hi all do you know how I can date this omega Deville

 

On a Quartz I'm not sure

 

I usually put on a clean shirt, wash my car, and ask nicely, it tends to work if the chemistry is there.

 

From the serial number on the movement, you will have to remove the caseback.

You could cross reference the model with the Omega Vintage database. http://www.omegawatches.com/planet-omega/heritage/vintage/

You could also look through vintage catalogues. http://www.old-omegas.com/

@Ritzwatch you got me laughing out loud to that one
