E. Howard & Co. Watch Movement Production Figures:
This research by Chapter 174 members Harold Visser and Clint Geller, to be published in Research Activites and News in the NAWCC BULLETIN, grew out of work presented by Clint Geller at the 2002 NAWCC Seminar in Boxborough, last October. Clint, and fellow Chapter 174 member Harold Visser, have been working assiduously with copies of the original E. Howard & Co. factory records to assemble a comprehensive and easily digestible picture of Howard watch production. They have been assisted in this effort by long-time Chapter 174 member and Smithsonian volunteer Bob Rolfe. The factory records are terse, incomplete and not infrequently enigmatic. Through a painstaking process of cross-correlation with movement data and visual images compiled by collectors over the past half century, he and Harold have been able to enhance greatly our understanding of these records and the information they contain. A major part of this effort, an expansion of Dr. Geller's 2002 seminar presentation, will appear next year as part of an NAWCC special publication. Certain key tables from this article, which were presented last October, will appear shortly on this website. Other unrelated data extracted from the records, such as a comprehensive listing of production purchasers, complete with dates and serial numbers of first and last purchases, will appear shortly as well.
