| Illinois Aluminum Movement Illinois Aluminum Movement watch. 3-O size. Grade 307. 17 jewels. Pendant set. Stem at 3 o'clock. Serial number 5,542,807, seventh in the run! Produced about the third or fourth year after Hamilton purchased Illinois. Illinois book shows this run starts at 5,542,801 and ends at 5,543,000, only 200 pieces (they may not have actually produced that many, depending on part supplies, success, and-or problems)! Though extremely light, most of us know how soft and problematic Aluminum is for threads, etc, so they may have decided Aluminum plates were a bad idea. Designated by a model number 307 S. A. W. (special Aluminum watch?), not certain what the abbreviation stands for yet. I have not found this model in any price guide, though a size 12 Aluminum movement appears in Cooksey Shugarts Price Guide to Watches. This movement is in excellent condition. Below you can see it in contrast to a standard nickel model 307 movement, the color and weight differences are dramatic. This might be the only Aluminum Illinois watch you will have the pleasure to see, enjoy! |
