Research Notes

Two runs of Grade 46 movements are listed in official Rockford Serial Lists. However, it is believed there are classification errors caused by transposed grade numbers. The first designated run [240,001-241,000] is listed as Open Face, Gilt, 11 Jewels, Model 4. Limited observations from this run have verified these characteristics. These movements are marked "Rockford Watch Co. - Patent Pinion - Rockford, Ill." in a black-letter style and are not fitted with a micrometric regulator. In contrast, the second designated run [248,001-249,000] is listed as Hunting, Gilt, 15 Jewels, Model 6, while the preceding run is designated as Grade 64 with features identical to the first run of Grade 46 movements. For this reason, it is believed that the preceding run [247,001-248,000] is actually Grade 46 despite being listed as Grade 64, and the second run of designated Grade 46 movements [248,001-249,000] is actually Grade 64. This would represent the only run of Grade 64 movements, so comparison with other known runs is not possible. No advertisements have been found for the Grade 46.
