In the year 1910 Junghans reached the production stage after they started in 1903 with the production of the first pocket watches. Oskar Junghans (1876 - 1927) developed the pocket watch with the caliber J9. Finally, a clock with full stems and massive boards that was not modeled after the American pocket watches which were often equipped with hollow stems and pillar movements.
I must confess: the clock was several years almost forgotten and placed in a drawer, it was a beautiful gift of a good friend. Only later I checked the caliber ticking in it and was stunned amazed that it is one of the few caliber J9. So far I have not seen live an other!
The watch is really a superb, with it escapement (stone pallets), with 15 jewels and a Breguet spiral compensation. The hands are original, the case is made of silver and rose gold, the blanks are yellow gold.
A very comprehensive overview of the different variants of the Junghans J9 and their use can be found on the highly informative page of Dirk Fassbender: Dirk Fassbender - Junghans J9
