My father in law has a couple of Rolex's. I am not well versed in the models or there worth. The mens watch he bought new in the 80's but he no longer has any of the accessories so its watch only and the woman's he bought second hand about 10 years ago. I can get a local dealer to vouch for the watches and the mens has been serviced regulary although he rarely wears it now since he has a Presidential with diamond marker and bezel that has taken its place. Any help would be greatly appreciated. Only thing I know about them is both are solid 18k gold although the womans model has a aftermarket 14k nugget bracelet.
