Howdy Experts! Ignorant watch guy here. I have inherited an old pocket watch. It came down through my father's family, which were in Ireland and Scotland. Would greatly appreciate any and all info that you can provide. The "works" are engraved "Elizabeth Gibbs" and "Cockburn fecit 1826". The back of the case (silver?) has "AM" stamped in it. Would love to know the age, country of origin, value, and anything else that you can tell me about it. Photos attached ... hopefully. MANY thanks.
