Research Notes

The Rockford Grade 79 was produced in a single run of 200 movements. Based on the Hunting Model 8 design, the Grade 79 features gilt plates with 15 jewels in red settings. Movements are marked "R.W.Co. - Rockford Ill. - Adjusted" in a blackletter ("Old English") style. The 1896 A.C. Becken catalog describes Grade 79 as "adjusted," indicating the movements were likely adjusted to temperature and isochronism.
