Herman: Editor Short orders were and still are a topic of discussion whenever Regina G. Stenger: Associate Editor watchmakers gather. From the amount of time and earnestness Donna Baas : Production Director devoted to the subject, the "how to handle it" seems to have never been solved. Adding to the confusion is the new kid on the block, Mildred Howard: Circulation Manager the quartz watch which will stop running with the tiniest amount Margie M. Brater: Circulation of soil in its gear box. TECHNICAL EDITORS: The most common short order that is seen today is battery re placement. This procedure has a built-in safety factor in it since David G. Arnold Wes Door the watch was not running when it was brought to the watch William Biederman Henry B. Fried maker. The crystal only is relatively safe, provided the glass has James H. Broughton Orville R. Hagans not shattered. But when we get to that stem and crown only Fred S. Burckhardt Ewell D.

President needed and fairly estimate the completed job. The customer Alice B. Carpenter, CMW, CEWS: 2nd V. President departs. You carefully wipe the case back and bezel as clean as Wes Door, CMW: Secretary possible. You either snap open the back or unscrew it. During Marvin E. Whitney, CMW, CMC, FAWI: Treasurer this operation, a tiny piece of soil drops into the movement. The watch stops. You fit the stem and crown. You blow out AWJ DIRECTORS: the movement but the watch doesn't run. You remove the train Jam es Adams, CMW bridge to find the obstruction, but that doesn't work either. James H. Broughton, CEWS You completely service the watch, including washing the case Fred S. Burckhardt and bracelet. Joe Crooks Henry B. Fried, CMW, CMC, FAWI The customer returns for the watch. You charge for a stem and a Gerald G. Jaeger, CMW, CEWS crown job. The customer leaves convinced that a fair and just Robert A. Nelson, CMW, CEWS transaction has just taken place. Howard L.
