Winding Wheel Patterns
Unlike previous 18 size Waltham movements, we find that the Model 92 movement has a sunken balance, something which is commonly found in 18 size Rockford movements. Unlike most full plate movements however, Waltham chooses to expose the winding wheels on the Vanguard movement. The winding wheels will be damascened according to grade, adding a visual aspect to the Model 92 movement that most full plate movements lack. "ATC" refers to the Appleton Tracy & Company grade.
