The ‘pendulum’ shown to the aperture at the front of the watch is a decorative device mounted onto the balance, moving as it oscillates and creating the appearance of a clock pendulum. By mounting the balance between the dial and movement, the backplate is treated in an unconventional manner and becomes of full plate design, allowing for a central cartouche which is signed and numbered by the maker and surrounded by two decoratively engraved half figures of winged nymphs. The symmetrically placed subsidiary dials to the dial for regulation and case/movement locking are also an unusual feature.

It is possible that William Sinclare was an Irish maker, as a Dublin maker of the same name is recorded as having worked during this period. The present lot signed William Sinclare, London may well be the same maker as William Sinclare, known to have worked in Dublin.  Baillie records a W. & Gordon Sinclare, Dublin working circa 1725 and a William Sinclare, prior to 1753.   Camerer Cuss Op.Cit also mentions a William Sinclare recorded as working in Dublin between 1698 and 1741, Good quality movement typical of the period (in later case).  William Sinclaire was working 1698-1741 and took five apprentices between 1725 and 1741.
