Research Notes
Meggers/Ehrhardt list Grade 101 as adjusted to temperature. However, catalog descriptions do not support this claim. Additionally, no Grade 101 movements have been found marked "Adjusted."
Some private label movements were upgraded to 15 Jewels (typically marked as such and would likely be considered grade "101 1/2").
Similar to the Grade 99 without the patent regulator.
