1970 Constellation CD 168 018 Valuation

[L77]

Hi, I have had an Omega Constellation CD 168 018 that I inherited from my grandfather twelve years ago but have no idea of it’s value. I have the original box & purchase warranty booklet from the date of sale in April 1970 and wondered where is the best place to have it valued? Thanks
