I do not have this watch . Some one asked me what balance staff is used for this watch. Does any body know? Do I need to ask him for more information , or is their only one staff for this watch

Should be a waltham #7864 staff

Hi Gary, Thanks for the info. Where does one go to find such data?

Melvin,
A good book to have to look up parts is Illustrated Manual of American Watch Movements by The E. & J. Swigart Co..I also use the Waltham Watch and Clock Material Book 1958 Edition..but there are many book that have this type of information in them..
