Britten’s dates/locations are: 1768-88; 196 Fleet Street (1769-75); 59 Fleet Street (1777-83); 90 Great Russell Street (1785-88).
Roger Smith, writing in Antiquarian Horology, says: ‘The goldsmith Timothy Williamson may have organised the making of his own distinctive cases, but their movements could well have been supplied by the well-known clockmaker, William Hughes, with whom Williamson has close links.’
Working dates for Hughes according to Britten’s were 1766-94. He worked at 119 High Holborn, an address which became famous as being that of Thomas Earnshaw, who took over Hughes’s business. Earnshaw, though already time-served when he arrived in London, looked upon Hughes as his mentor.

A similar style watch by Williamson, number 2780, was offered, but not sold by Antiquorum at a Geneva sale in October 2000, with estimate of $14,000 - $17,000. That one’s diameter was no less than 140mm.
Hughes’s own watches tended to be plainer, though of high quality, and he signed the dial:
