Remember to use the serial number on the movement, not the case.

Hamilton used a date letter instead of numbers to replace the first number of the full serial number on some of their movements. The table below shows the letters used for the 992B, 950B & (4)992B movements.

Grade 992B - First letter C + serial no. Grade 950B - First letter 2B + serial no. Grade (4)992B - First letter 4C = serial no.
