Fine And Rare Pair Case Duplex Escapement Silver Repeater Coach Watch

This is a very rare example of a huge pair case coach watch made in Austria in the late 1700's/ beginning of the 1800's by the well-known maker Franz Lehner. The Lehner family is placed in the history of horology as one of the longest clock makers and watch makers line, starting in the late 1600's, ending at the beginning of the 1900's. The Lehners' reputation was built on high-quality craftsmanship and innovation, a lot of the well-known makers of the Austrian empire started their apprenticeship at the Lehners' workshops. Carl Suchy, later known as Carl Suchy and Sohne was one of Lehner's apprentice, finishing his apprenticeship in 1812, around the time when this coach watch has been built.
The watch is encased in a solid silver case attributed to an earlier maker.
The back of the case is fully engraved. Traditionally, the watches of that time required an outer case. The exterior case of this watch is made of two metals (silver and copper), covered with stingray leather. The back of the case is decorated with holes beautifully finished with silver color eyelets, allowing the sound of the bell to travel outside of the case.
The fine-crafted movement is made in a traditional Austrian style, with a rare duplex escapement; by pressing the button located on the right side, the watch will strike the hour on a high-pitch bell. 
The maker also allowed an alarm function that can be easily set by moving the posterior hand on the dial.
The hand-engraved dial is made of silvered copper.
This watch is a rare example of Austrian craftsmanship, and due to its condition, it can be placed in a valuable collection.
