        The Harwood automatic wristwatch - 1

John Harwood of Bolton, with his later workshop in the Isle of Man, is credited as inventor of the first automatic wristwatch. This  example of a Harwood 9ct gold bumper automatic was produced by Fortis circa 1928. The time setting is achieved by turning the bezel that then engages with the setting train. A short reverse turn disengages the setting link to the running position indicated by a red flag in the dial window at 6.
        The Harwood automatic wristwatch - 2

John Harwood of Bolton was the inventor of the first automatic wristwatch. This rare example of a Harwood 18ct gold bumper automatic was produced by Blancpain circa 1929. According to several adverts it was intended for the Spanish market. Harwood watches produced by Fortis had a setting mechanism driven by rotating the bezel. However, in this model the watch back is rotated such that the setting wheel (arrowed) is turned by teeth cut on the inside rim of the back itself. A short reverse turn disengages the setting mechanism, as indicated by the red mark in the window of the dial.
