Hello. New member here. I need help in identifying this antique pocket watch. I am a novice and any information I received was from extensive google searches. I believe I have a Hamilton snap back case and possibly M.J. Tobias movement. I have many questions. 1. Is the Hamilton case silver? I could not find any markings. 2. Is the Hamilton case a salesman sample? It has a glass, open face back. 3. Is this an actual M.J. Tobias movement? The engraved scenic landscape along with the beautiful accents around the Roman numerals has me leaning in this direction. 4. Is the movement face gold? Once again, no markings found. 5. What is this worth? It does not work but the movement hands can be manipulated by center dial in the rear. Thank you in advance, Philip.
