Two more Unidentified Omegas...

So amongst my grandfather's watches are two more Omegas I haven't been able to identify. One is an unknown quartz Seamaster with no identifying markings, and the other is an automatic DeVille with a few numbers I haven't been able to track down the meaning of, other than the code for the case and integrated bracelet being sterling silver. Any help with these would be much appreciated



The unknown quartz Seamaster



Silver automatic DeVille



DeVille's ID numbers, and evidence that I need to give it a good clean

Alright I was probably asking for that one 😜 I guess I was meaning what type of Seamaster and what type of DeVille. I'll see if I can't open them up and get at the info inside
