The Vintage Wrist Watch Company has dated this piece to the 1910s.
The movement is signed Elgin and it has the serial number 17,989,325 which dates it back to 1913. The movement is ticking away nicely and the time keeping is good to within around two minutes over 24 hours.

The movement is protected by an inner hinged dust cover. The cover has been scratched with the dates 2.6.1919 and also 27 Feb 1920; there is other writing but it is difficult to read.
The watch measures 50mm diameter excluding the winding crown, stem and loop. The inside of the case back is stamped ‘sterling’ together with the name of the watch case manufacturers, Keystone Watch Case Co, USA. The inside of the front cover has a 1918 date and name scratched into it.

The watch has a later plastic lens.
The enamel dial is signed Elgin. It is in good condition with just a faint hairline crack between 7 and 8 and another running from the centre towards number 1; they are not too detrimental at all.
