LANG & HEYNE -Caliber I Movement

The typical three-quarter plate has been state of the art in the building of fine movements in Saxony since the end of the 19th century. LANG & HEYNE “Caliber I” is an honest tribute to that 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 that holds the lever anchor is set in a gold chaton, held by deeply blued steel screws.


The meticulous anglesite finishing, polished by hand with pewter, of the anchor bridge and the balance cock as well as the slit golden screws of the balance wheel create charming reflections of light. The polishing of the winding wheels gives the impression of a shining sun. The ultimate in beauty, however, is the sparkling diamond, crowning the balance. Majestically it is placed on top of the hand engraved balance cock, harmonizing perfectly with the elegantly swung swan-neck fine adjustment.


The balance spring bent markedly upward in its last winding ensures smooth pulse of the shock-resistant gold-screw balance wheel. “Caliber I” is equipped with a second hand stop mechanism, in other words, 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.
