Job Number 180050

Here's an Illinois Watch Company grade 304, 16 size, 17 jewels, made about 1912. 

It's a private label, "Mermod-Jaccard & King, St Louis" on the dial,
"Standard, St. Louis, USA" on the movement. 

See the entire album for this project here.

Nice looking bridge layout on these... As usual on American watches, the separate fingers 4th and escape are false. It's really one part.

The watch movement's serial number is hand scribed at the factory on the underside of an arm of the balance wheel.

I enjoy seeing signs like this of a human connection in the manufacture of this antique.
