The firm of Charles Hutton Errington, Coventry, later purchased by H Williamson Ltd, one of the pioneers of English machine-made watches - note the use of stem setting, rather than the usual English pin-set keyless work.
Founded by Henry Williamson in 1865, they became an increasingly more important English wholesale and retail firm as they acquired the business's of Charles Hutton Errington of Coventry in 1895, the remnants of the English Watch Company in 1897 and the Swiss business of Suter & Co (Buren) in 1899. With a head office in London, Williamson produced mainly machine-made pocket watches and some wristwatches (in Coventry), and are also known to have supplied government contract military watches and Deck Watches.
NB: This is Williamson's 2nd highest 'B Grade' of movement examples of which are rarely encountered, even less so in a Thoms case and in such good condition.
Case with still crisp engraved dedication on dome and the button lacking part of its gold shell, otherwise almost mint and showing few signs of use. The movement in similarly good condition but the dial with the usual hair cracks. Serviced and guaranteed.
