The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a stem-winding movement which is working nicely.
The movement is protected by an inner hinged cover which has light surface scratching, nothing too serious at all.

The watch measures 47mm diameter excluding the winding crown and the loop so slightly smaller than a standard pocket watch. The case is niello ware which is where a black mixture, usually sulphur, copper, silver, and lead, is used as an inlay on engraved or etched metal, especially silver, in this case 800 silver. It is added as a powder or paste, then fired until it melts or at least softens, and flows or is pushed into the engraved lines in the metal. There is some rubbing to the case, mainly to the back.

The winding crown pushes in to open the front cover. Inside, there is an acrylic lens which is in good condition.
The dial looks good to the naked eye. If viewed closely, there is a crack just beneath number 5 but it is quite difficult to see with the naked eye.
The watch comes in a new presentation box.
