Grade 122 The grade 122 was the immediate predecessor of the 176 high grade 6 size. It has a gold (plated) train and 17 jewels and is adjusted. It does not have the patent regulator that appears on the 176 (and the 16 jewel 168). The example has had too much time in the cleaning bath and has lost some of the gold from the wheel work.
