The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a stem-winding movement which is working nicely.

The watch measures 50mm diameter excluding the winding stem and the loop. The case is Continental silver and the back cover has the early Omega logo. The case is in good condition, perhaps a gentle indentation to the back. Handsome decoration to the back of the watch, including a vacant cartouche.

The glass lens is in good condition (some reflection showing in the photos).
The lens looks lovely to the naked eye. If viewed through a magnifying loupe, there are three short very faint hairlines between 2 and 3.
The watch comes in a new presentation box.
