Research Note: Waltham Serial Lists designate this run as Grade Riverside with 19 Jewels. #25680784 [NAWCC]: Verified as Marked "Crescent St." and "21 Jewels - Adjusted." Damaskeening pattern is consistent with the "Riverside" grade produced in this era and does not match typical "Crescent St." movements from the late 1910s. This suggests the some movements in the run were upgraded from "Riverside" to "Crescent St." #25680738: Verified as Marked "Riverside" and "19 Jewels," consistent with factory serial lists.
