President's Message By Charles Cleves There seems to be a growing spirit of cooperation between A WI and several kindred organizations. I was speaking with a couple of material supply house executives last week, and they reported how impressed they were when Bill Ewbank came to the annual Jewelry Industry Distributors Associa­ tion (JIDA) meeting to give a talk about A WI and its activities. For the past couple of years we knew we were on the right track at A WI. Now, it seems that other people and organizations are starting to take notice and are becoming more interested in A WI. Last month, upon our invitation, Doug Cowan sat in on part of our strategic planning committee meeting. Doug is the Second Vice President ofNAWCC and is Chairman of that group's planning committee. We discussed several ideas on how we could help each other. One idea was to exchange columns in each other's magazines. There was a positive feeling among those present at this meeting that our two organizations can continue to build a better relationship in the future. Another direction that has recently developed is the AWl Jewelry for Watchmakers Program. Members and other interested persons can now increase their earnings potential by doing some of their own soldering and jewelry repair. Just the hands-on practice will give a better idea of which jobs cannot be done. The first class has already been taught at AWl's headquarters. The Jewelers of America (JA) has expressed interest in recognizing this program as credit toward their own certification program. This extremely large organization is also interested in learning more of what A WI is all about. I think we are definitely on the right track. We now have the respect of many of the organizations within the jewelry and horological fields. If we continue making progress at the rate we have shown in the past couple of years, there is no telling where we will be five years from now. Executive Director's Message By William J. Ewbank By now you may have noticed that we've been fooling around with the cover again. Actually this month's cover is reporting a significant event. The cover displays the new home page for the AWl internet website and supports our feature article by Fortunat Mueller-Maerki. We've noticed that our old site, as drab and tired as it was, proved to be the single best source for new members. Adding some life, color and action to the new home page was an easy decision. By the time this magazine arrives at your home, the new site should be active. If you are on-line, look us up@ www.awi-net.org. We are also reaching our busiest time of the year at A WI headquarters when we prepare for our annual Board of Directors meeting, prepare a new annual budget and review and report on the successes and failures of the year past. It has been a very introspective time for me. As our readers will recall, my fiscal year began on the operating table and included a lengthy period of recovery from two major surgeries and radiation therapy. I learned that I am indeed mortal and that no matter how tough you think you are; if you are sick and injured, you simply cannot perform at your peak. If I were grading myself, I'm afraid I would have to give an incomplete. A major responsibility for the Executive Director is to present a "State of the Institute" message at the annual Board Meeting. This report not only covers the highlights of the past year, but is also the opportunity for the executive to make recommendations to the Board for future action.
