An unusual watch because of its layout, its high standard of execution, and because it employs an early time zone system.The history of multiple time zone indications is interesting. According to the London "Annual Register" for 1821, Mr. Kuchajewski of Warsaw, Poland, constructed "an astronomical watch, which indicated the time differences in the principal places in various parts of the globe". Kuchajewski's watch was presented to Emperor Alexander I (1777-1825), who "assigned him a sum to enale him to continue his important scientific labor". In the last quarter of the 19th century a number of patents related to multiple time zones were registered, the early ones were based on rotating single dial with names of cities painted radially, with inner 12-hour reference dial. The first patent, No. 1820, was registered on December 12, 1889 by Dr. Tinney of Berlin. A year later, on August 22, 1890, Louis-Philippe Wuillemin of Soutz registered patent No. 2523, describing a system very similato the one in this watch - but about 60 years later. Yet another system was employed for lot No. 114. The patents that followed later focused on ways of setting the correct time for any given city.Johan Pechan is listed as working in Vienna from at least 1794 onwards.
