Catalogue Note

The back of the outer case has the crest of George Spencer (1738-1817), fourth duke of Marlborough, together with the Order of the Garter and motto in relief. A surviving Vulliamy day book records that the movement, dial and hands were sold to the Duke on 31st January 1804 and fitted, according to his request, to previously supplied cases. At the same time, the old movement was fitted to a new case for a total of 120 guineas. A search made by Roger Smith into Vulliamy's records held at the Public Record Office - the extant day books start in the 1790s - revealed the entry [C104/58/1, Day Book 31] which describes the movement, stating that it included "one of the best coiled thermometers," this is visible to the backplate and is a bi-metallic spiral compensation. Vulliamy abandoned the spiral system of compensation soon after this watch was made and continued to use a U-shaped curb.

The Duke of Marlborough took a keen interest in science.  In 1786, he was made a fellow of the Royal Society, and indeed would have enjoyed owning a watch with this advanced mechanism. He perhaps had a sentimental attachment to the old case, hence was keen to be able to use it with his latest watch acquisition.
