I think you nailed the ID on this one...
Gosh...I gotta check, but we may have some indication of a variant too.
I think that both are identical, DE "G"
+1, cool watch man.
This is a beautiful watch Denis, I like this one a lot. I agree that it's a Diamond Excellency. Like Jaroslav's I'm tentative as a "G" variant as the advert states 'yellow or white'.

Thanks for the comments,sometimes ten bucks does get you something good on the Bay.
I'm good with Tentative Diamond Excellency variant "G".
No help from the price lists on variant designation for case gold color, as the Diamond Excellency series/variants were most likely released in 1966- after the last price list we have (1964).
