Research Note: Waltham Serial Lists designate this run as Grade "A.T.&Co." with 21 Jewels. However, #12020320 has been reported as featuring 17 Jewels, consistent with other Model 1892 runs of the A.T. & Co. grade. For this reason, the run has been changed to "17 Jewels" in the database since the "21 Jewels" reflected in the factory serial list is likely a mistake. Future observations and reports from this run may provide more insight into this discrepancy.
