I am replacing the balance staff on a Waltham grade 845 model 1892 but while trying to measure the staff I dropped it on the shop floor. lost and gone forever. The right replacement should be either a 1703 or a 1703A can someone tell me which one it is? Serial # of movement is 16006052 with a double roller table. Thanks.

Also be aware that the 1892 was modified throughout its lifetime so you will probably have to buy a few staffs to find the one that actually fits.
