I need help locating the serial number on case ref 175.0032.1

It is a speedy reduced with a 3220a movement. I couldn't find it on back or on the movement.

it should be down the side of the back of one of the lugs but it is very very small.

Thanks Matt! I have seen the question asked 10 times and have never seen an answer!
