About the inscription "Le Roi a Paris"
The marking of the dials "Le Roi a Paris" is a marketing ploy, the desire to attract buyers. At the end of XIX - early XX centuries the German watch companies used the name of the famous French watchmakers dynasty of the XVIII century.
Julien Le Roy the father (1686-1759) was a court watchmaker of Louis the XV and was glorified by Voltaire as the inventor of the clockwork excelling the quality of the English ones, which had traditionally been considered to the best in the world. Pierre Le Roy the son (1717-1785) (it was him whom Pushkin describes as "glorious") not only kept his father's inventive activity, but also explored the abnormality of chronometric measurements which he had discovered earlier. He was awarded the prize of the Paris Academy of Science for his works, especially because they had an important meaning in military and navigation business.
Many watch companies in Germany used this label, among them there were «Shlenkler-Kienzle», «Yunghans», «FMS and PHS», «HAU» and others .
