You should have the watches checked by someone who can verify the quality of the cases and bracelets. The definition in the photo of the one is indistinct, but the other one shows .750 which means 18 karat. Have the cases and bracelets tested to see if the stampings are true. With gold at over $3,300 (US) per ounce, the price yield should take that into consideration. Genuine Omegas won’t have these types of stamping on the exterior of the case back, so don’t expect the value to be much higher than scrap value.
I'm sorry to say that I agree - don't waste your time and/or money having these watches tested.
No-one is going to make a gold watch and then (badly) brand it Omega.
Both appear to be snap-back cases - if you can be bothered, remove the backs and you will find an inexpensive non-omega movt inside each.
If they are being sold in a charity store - if it is not illegal where you are - mark them as copies and sell them as novelties for a few dollars/pounds/euros.
