Input to this 135.020

Hi!

I have been looking for a honest and solid gold omega in good condition for a while and have came across this one in the pictures below. As I have way less knowledge than you, I would like to check with you whether the crown really is correct for this ref (35.020) or not? As I understand it, it should be a smaller one.

Sorry for the not very sharp pictures. 😀

Also, any other findings are of course appreciated. The watch has recently been serviced!

Gonna try a small bump here, although I guess it’s the wrong crown and maybe not a great pick😀
