These are Elgin 12 size and 16 size pocket watch movements. The 12 size is an open face 17 jewel “GM. WHEELER watch and the 16 size is a 7 jewel open face movement. The 12 size has a good balance wheel and staff, while the 16 size has a broken balance staff. The real prize is the GM Wheeler as it is clean and does tick. Nice movements for the Elgin movement cabinet. Just the use of a single part from one of these movements can save a future repair.
