Notes:  This is one of the heftiest pre-Accu-Swiss Bulovas I have owned, with nearly square dimensions that are in keeping with the recent trends.  It was built for heavy duty, and it has seen it.  Other than putting it in line for a new crystal and service, I will allow it to show that it was worn and appreciated in its 51 years.
