Silver paircase hallmarked London 1738, both cases stamped HD (Henry Duck, Aldersgate), the inner with equation-of-time watchpaper. Fullplate fusee movement with square balluster pillars and nicely pierced and engraved cock and slide plate, the potance-plate also numbered between the plates, as usual with this maker. Verge (recoil) escapement. Steel balance, spiral balance-spring. Lovely original 2-piece silver champleve dial with decorative gold half-hour pins, the centre signed on twin banner cartouches WINDMILLS LONDON, blued-steel beetle & poker hands. 50.5 mm diameter.
Thomas Windmills, a fine watch and clock maker, with examples of his work in most museum horological collections worldwide – see the book Joseph and Thomas Windmills… by Jim Neale. NB: This watch dates from the end of the firm with the death of Thomas in 1737 and is one of, but not the last of those recorded in the firm’s number sequence. Thomas served as Master of the Clockmakers’ Company in 1718.
Nicely detailed watch cases by Henry Duck who first registered this stamp as a smallworker in 1735 – see Grimwade. The stamp is not conjoined as stated by Priestly but the typeface is unusual and rather archaic, and is not at all common.
Some solder around the base of the pendant inside the case, as usual, but the pendant is the original, and some rust damage to the Gravell & Son watchpaper. Otherwise in good original condition, a fine example of the Windmills later work – I have seen very few that are as good, most that survive having had, at least, their dials replaced. Serviced and guaranteed.
