Here is information and pictures on a Waltham watch I bought recently. The front bezel I have not been able to get off. I was able, after some hours, to get the rear of the case off using a piece of Latex, which revealed the S & R Co. on the inside. Getting the back off gave me the S/N 16978714 coming back to: a Grade: Sterling; Model: 1883; Estimated Year: 1908; 18s; 15j; Openface movement. I had never seen the Sears and Roebuck logo before so I had to look it up. Thank everyone for so much information. I haven't been able to digest it all yet. I have included a few pictures. Any additional information is very much appreciated!
