Movement as well as case design of these watches intended for the Turkish market was already outmoded in 1817 – and even more so in later years; nevertheless Edward Prior and some of his contemporaries such as George Prior (II), George Charle, Markwick Markham-Perigal and Isaac Rogers specialized on this type of watch because there was an ongoing demand for them on the Turkish market – be it from tradition or from a true love of the elaborately ornamented movements and cases. It is quite possible that many of these watches – the one we have here are among them – never even left England, because their exotic beauty had its devotees in their own country too. Very often these buyers kept the watch safely in a drawer like jewellery, which explains the mint condition of some of these marvellous pieces – as is the case with our watch. The exquisite gold enamel cases were probably created by goldsmith Augustus Newman in 7 Plumptree Street, Bloomsbury, London, whose mark appears for the first time on November 4th, 1813; we still do not know who painted the gallant scenes on the outer cases though.
