One of Adolphe Mottu's watches is in the Victoria Museum in Melbourne, Australia, nr. inv.ST 17677. Watch examined by Frederick Dent, supplier to the Queen of England. From 1814 onwards, Dent supplied watches to the four corners of the British Empire. It was also Edward Dent who helped establish Greenwich time. He obtained a Royal Letter Patent from Queen Victoria in 1841, which was later renewed by Tsars Alexander III and Nicholas II. The watch was therefore revised after 1841.
