I have inherited an Omega watch that has been in the family for decades. I am not a watch person so I am trying to decide whether to sell it or take the value in gold. It is an old watch, not the type popular now but it is 18k watch and bracelet. 21 jw / grade 111 / mvmt #26066965 / case # 941556/8132. It is in great shape but it does not have the original box. If I were to sell it, where would be the best place? I appreciate any help!
