Danner: Co-Editor Regina Stenger: Associate Editor hat is an identification mark? From time Harold J. Herman: Senior Technical Editor W immemorial it has been a scratch put in Donna Baas: Production Director the back of a watch case by a watchmaker so he could tell at a glance if he had ever worked on the Nancy Wellmann: Business Manager watch before. Some of the scratch marks were really Margie M. Brater: Circulation Manager unique! Some would tell the watchmaker only if Mary Sansalone: Seminar Coordinator he had ever worked on the watch, while others would tell the watchmaker exactly what he had TECHNICAL EDITORS: done to the watch, as well as the date the repairs were done. This was ingenious! A repair person did James Adams Wes Door not have to depend on a vague description in a Robert F. Bishop Henry B. Fried repair log to tell him he may or may not have worked on that particular timepiece James H. Broughton Ewell D. Hartman before. After all, there were a lot of watches sold that looked exactly alike. Some scratch Fred S. Burckhardt Robert A. Nelson marks had symbols to represent the particular watchmaker. One in my hometown has Charles Cleves the name of Rex. He uses an "R" with the down stem marked with an "x". Another in Archie B. Perkins my state circles the job number of the timepiece with the date on the outside of the Steven G. Conover Marshall F. Richmond circle. Another uses his AWi registered identification mark (case scratch) with a code for Joe Crooks Marvin E. Whitney what he did to the timepiece: 1 ; clean and overhaul, 2 ; staff, 3 ; mainspring, and so forth, and ended with a date. So, what is an AWi identification mark and how is it different from the old AW/ OFFICERS: original mark that each individual watchmaker came up with? An AWi identification mark is a nationally registered mark given to a watch­ Alice B. Carpenter, CMW, CEWS: President maker/clockmaker when he/she joins AWi. It is also available to others upon request. Wes Door, CMW: First Vice President One need not be an AWi member to request an identification mark. A record of that James Adams, CMW: Second Vice President person's mark is kept on file at AWi headquarters. What is the purpose of this? I'm glad you asked that question! Fred S. Burckhardt: Secretary Let's say that an unidentified body is found and he or she is wearing a watch. Marvin E. Whitney, CMW, CMC, FAWI : Treasurer If that watch was repaired by a person who used his AWi identification mark, the law enforcement agency can request the identity of the repair person. The repair person can AW/ DIRECTORS: then provide the police with the identity of the owner of the watch. The identification mark also satisfies the original intent of marking the case so William Biederman, CMW that the repair person will know what repairs were done and when. Robert F. Bishop, CEWS The national registered identification mark is not confined to watches. How many of you mark the clock movements? If you don't, why not? How better to know if James H. Broughton, CEWS and when you worked on that particular movement? My memory isn't all that infallible. Buddy Carpenter, CMC, CEWS A lot of the clock movements are so similar that after you've been in the business for 20 Henry Frystak, CMW years, they only seem like you may have worked on them 5 years ago. Not so good if Ewell D. Hartman, CMW you need irrefutable evidence of what was done and when it was done. Gerald G. Jaeger, CMW, CEWS, FAWI Many collectors and jewelers mark "important" pieces with their identifica­ tion mark. It aids in recovery should the items be stolen. Donald R. Loke So, why don't you use the identification mark assigned to you? If you don't Robert L. Macomber, CMC remember yours, contact AWi Central. Encourage friends in the business to ask for one. Marshall F. Richmond, CMW We have an identification mark committee, chaired by Robert Macomber of Arizona. Bob is very enthusiastic about the ID mark program. If you are interested in presenting a program about the ID mark system, contact Bob Macomber. He will see to Paul D. Wadsworth: Affiliate Chapter Director it that you have the information you need to put on your own program. How to contact Arnold Van Tiem: REC Director , Bob?
