The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a good quality stem-winding movement, identified as a Regina, which is working nicely.
At the time this watch was made, Omega wanted to increase their share of the watch market in Canada.
In order to get around this issue, and to increase their sales, they purchased the Regina Watch Company from Louis Maier who first registered the name in 1888. Louis Brandt subsequently registered the Regina name to Omega.

The movement is protected by an inner hinged cover.
The watch measures 50mm diameter excluding the winding stem and the loop. The case is silver and there are hallmarks inside the two case backs for London (import mark), 1918 with an importer's mark for Louis Weill, a high class retailer and importer who often imported Omega watches. The case is in good condition, just some slight unevenness to the case back.

The winding crown pushes in to open the front cover. Inside a later gold plated bezel has been fitted. The acrylic lens is in good condition.
The dial is in good condition and has blued steel hands, including the special half hunter hour hand so that the time can be read when the front cover is closed.
The watch comes in a new presentation box.
