Job Number 180099

This next Elgin is a grade 368, 18 size, 17 jewels, made about 1909. 

This is a high-end model, and although this example has quite a bit of wear and tear, it's running quite well.

I am often asked about the numbers and codes found scratched, usually, in case backs. These are watchmakers' marks, made by people that serviced the watch in the past. They have no standardized meanings.
