The Vintage Wrist Watch Company has dated this piece to the 1910s.
There should be a fitted inner cover over the movement but this has gone missing over the years. The silver inner cover is still present. Winding key included.

The watch measures 52mm diameter excluding the stem and the loop. The case is silver and there are hallmarks inside the back covers for London 1918. The maker's mark is for Walker & Hall so this tells us that the case is not original to the movement.

There are a couple of small “dings” to the case, and some unevenness to the case back.
The watch glass is in good condition.
The signed dial is in very nice condition.
The watch will be sent in a new presentation box.
