OMEGA OMEGA Antique Pocket Watch

This is an antique Omega pocket watch.
It's a manual-winding watch.
I bought it about 30 years ago at a local antique shop.
It's quite rare, so I used to display it in my shop!
I had it overhauled a few years ago, so it's running properly.
The back cover opens easily, allowing you to see the movement. It's more of a collector's item for appreciation than for practical use. A model very similar to this one is featured in the Omega Timepieces Chronology, and it appears to be an early type from about 100 years ago.
I will include the documentation with it.
