Since the end of the 19th century in Saxony, the typical three-quarter plate has been built using state-of-the-art techniques for fine movement. Our CALIBER I is an honest tribute to this heritage, emphasizing typical elements not only of function, but also of beauty.
Big shining rubies, set in gleaming gold chatons, create a balanced contrast to the silver finished plate. Even the smallest of the stones, the one holding the lever anchor in place, is set in gold chatons and secured by deeply blued steel screws. The meticulous black, hand-polished chamfer finishing of the anchor bridge and the balance cock as well as the slit golden screws of the balance wheel creates charming reflections of light.

The ultimate in beauty, however, is the sparkling diamond that crowns the balance. It is majestically placed on top of the hand-engraved balance cock, in perfect with the elegant swan-neck fine adjustment. The balance spring is bent markedly upward in its last winding to ensure the smooth pulse of the shock-resistant gold screw balance wheel.

CALIBER I is equipped with a second hand stop mechanism. When the crown has been pulled out, a spring gently bends itself around the balance shaft and the second hand stops, hence permitting the watch to be set accurately to the second.

Friedrich August

The FRIEDRICH AUGUST I model is classy and noble, with the look of a pocket watch around 1900.


Like its namesake, it concentrates on the essentials, portraying the timeless elegance of JOHANN. The bipartite dial is available with a classical white enamel dial or with a galvanic black dial in solid silver.


Enamel lives. Scarcely any other material gives the dial of a fine watch such a persuasive and charming character. See the impressive result in our CHAMPLEVÈ – a special manufacture of our JOHANN model with CALIBER I.
