Me: "Solid Gold 19K (0.800) Case by Omega'
Where is the case marked Omega?
Seller: I don't see any outside the case other than on the knob.
I don't think I have ever seen on the old antique gold watches
their insignia other than on their respective winding knobs,
even on Patek Philippes.
Thanks for your inquiry.
