Notes

Dial, case and movement signed. DIAM. 60 mm. THICKNESS 25 mm. This watch is illustrated in The Jurgensen Dynasty by JOHN KNUDSEN, p. 100, 101 and 102. In the book there is an interesting mention of this exact watch: The famous Russian astronomer COUNCILLOR OF STATE SHUBERT wrote about this chronometer, in the journal of the IMPERIAL ACADEMY OF SCIENCES in Saint-Petersburg "....Mr URBAN JURGENSEN in Copenhagen constructs chronometers which are equal to the best English ones. One of these chronometers in gold, made with the greatest accuracy and the highest levels of luxury, which the KING OF DENMARK commissioned from Urban Jurgensen to be presented to the first person in Russia to sail around the world, COMMANDER KRUSENSTERN, therefore bears the engraving: FROM FREDERIK VI TO COMMANDER VON KRUSENSTERN. Its rate was tested for over a month by our observatory at the Imperial Academy of Sciences. In the trials, the chronometer's precision was found to be so excellent that only few chronometers could be placed on a par with it."
