Hi, I owe a limited edition of a Rotary watch and would like to know how much it is valued. I have attached a few pictures. Essentially, this watch includes a gold ingot that is stamped with the logo of the Swiss Bank Corporation, which merged with UBS in 1998 https://en.wikipedia.org/wiki/Swiss_Bank_Corporation#Merger_with_Union_Bank_of_Switzerland I think it was only sold to employees of the SBC, one of which was my grandfather. If you are not able to provide me with this information, could you please direct me to someone who could? Thank you. Kind regards, Stephane Unfortunately cannot insert pictures. It is in an unworn condition.
