Product Description

Here is a very rare 18th century antique pocket watch by Cumming and Grant made in 18ct yellow gold, set with pearls, an enamel back, enamel dial, rose cut diamond end stone and further rose cut diamond on the bow. This is a pocket watch not to be taken lightly nor not truly appreciated for its incredible quality, rarity and beauty.
A small piece on the eminent watchmaker Alexander Cumming and his nephew, John Grant (Senior).
Alexander Cumming (1733-1844) was a famous Scottish watchmaker and inventor who not only made this pocket watch but invented the design of the flush toilet, that had been invented earlier by Sir John Harrington. The S-trap was invented by him in 1775 to retain water permanently within the bowl to prevent sewer gases from entering buildings. It can still be found in today’s plumbing modified as a U- or J-shaped pipe trap located below or within a plumbing fixture.
He was so well regarded as a watch maker, that he was appointed a member of the commission set up in 1763 to adjudicate on John Harrison’s infamous ‘timekeeper for discovering the longitude at sea’”. He was commissioned by King George III to make a barometrical clock which was the first accurate recording barograph. This took him two years to make and he was kept on a retainer to continue to maintain it. He also wrote books about watch and clock mechanisms, about the effect on roads of carriage wheels with rims of various shapes, and on the influence of gravity.
In 1770 with John Hill, he is credited with the invention of the microtome, which is a machine for making extremely thin slices used in slide-preparation.
John Grant (Senior) was the nephew of Alexander Cumming and later with his son also call John, continued to produce high grade pocket watches.
