How much is a Cordell 36 Swiss windup watch worth?

I have the same problem I have I thinka 1979 corDELL "36" lined in gold with 36 diamonds circled in the face of it. I have googled this for a while and I can not find a value, the company, or even a duplicate watch. I have found a box that it comes inon ebay for sale. Also another corDELL watch on ebay for sale but its a newer one. I dont know if this a rare watch or what? I'd love to find out.
