18K Two Train Grand & Petit Sonnerie With Trip Repeater

With Signed Original Wood Case including 2 alternate original dials

Beautiful carved and engraved massive 18K hunter cased Grande Sonnerie.  This watch by C. A. Montadon from Locle, Switzerland has a tandem wind 37 jewel movement with diamond endstones is a Grande & Petit Sonnerie and trip repeater which will chime the hours and quarter hours as time passes automatically.  The fully jeweled movement will chime the hours every hour by itself and will chime the hours and quarter hours every quarter hour (Grande Sonnerie).  It has 2 switches on the bezel; one for sonnerie or silent, and another to select Petit Sonnerie or Grande Sonnerie.  In the petit sonnerie mode the watch strikes the hours every hour, but at each quarter hour it chimes only the 2 tone quarter strikes without the hours, much like many striking clocks.  Winding the watch crown clockwise winds the watch and winding it counterclockwise winds the sonnerie.  There is a button in the edge band that, when pressed, makes the watch strike the hours and quarters on demand.  The case, dial and movement are all in very good working condition, correctly chiming the hours and quarters as time passes.  The watch is signed C A Montadon on the case, the movement and the original wood box.  The box has an inlaid brass shield and contains a spare alternate silver engraved dial and a clear glass dial with gold index numbers to display the magnificent complicated dial side of the movement.  The silver dial is very similar to many other dials like this on other C A Montadon watches from this period.  The clear glass dial has gold index numbers that are very worn because the numbers are on the outside of the dial where they were touched and cleaned by prior owners of the watch.
