This watch belonged to my Great Uncle who was an engineer for the New York Central RR. It came to me in a Bunn Special box but it is a Ball Cleveland.
The serial number on the movement is B648300. It has 23 jewels. It has blue hands and black numbers.
Is it just in the wrong case or is there a link between Bunn and Ball? Also does 17, 18, refer to size? If so can someone tell me what size this watch is?
Any info or insights will be appreciated.
Thanks an best regards,
