The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a hand-winding movement which is working nicely.
Sometimes manufacturers liked to add fictitious patent numbers to imply that the movement contained a unique feature or to suggest that it was protected by a patent.

The watch itself is a very good size at 40mm diameter excluding the onion winding crown and fixed wire lugs. The inside of the hinged case back has Swiss hallmarks for 800 silver. Overall the case is in good condition, just some slight unevenness to the centre section of the case.

The watch glass is in good condition, just a couple of small chips to the bevelled edge.
The white enamel dial has two hairline cracks radiating from the centre, out towards the perimeter, and a shorter one which just runs down to the sub seconds dial. Blued steel hands, a subsidiary seconds dial and outer minute markers.
A new leather strap has been fitted.
The watch will be sent in a new presentation box.
