Research Notes

Rockford Serial Lists indicate a total of 551 Grade 920 movement were manufactured, generally alternating with runs of Grade 915 movements with small batches. The 1903 Oskamp, Nolting & Co. catalog describes the Grade 920 as "adjusted to temperature and positions." Movements are marked "Rockford Watch Co. - 17 Jewels - Adjusted" in fancy and simple serif style.

The Grade 920 and the "sister" Grade 820 were produced during the 18-Size model transition from 7/8 to 9/10. All Grade 820 runs are listed as Model 7 in the factory serial lists. However, observations have been recorded of Model 9 Grade 920 movements.

The c.1907 Rockford Catalog ("The Name Rockford Designated a High Grade Watch") includes an illustration of the Grade 820 movement (the "sister" hunting grade), consistent with the traits of a Model 8. In contrast, other 18-Size movements offered within the catalog are clearly illustrated as Model 9/10 movements.
