This pocket watch measures one and 5/8 inches in diameter. It was manufactured sometime between 1890 and 1904. The watch, itself, was manufactured by the new Columbus watch company, numbered 357721. The case was manufactured by Essex superior, case number 631534. It is yellow and rose gold, with a pagoda motif, with a single diamond on one side of the case. This watch has been in my family for four generations. I’m looking to find it a good home. This watch has my grandfather’s name engraved inside the case.
