THE NOBILITY OF A DIAMOND ENDSTONE.

The diamond endstone of the balance bearing was once a hallmark of the superior quality of A. Lange & Söhne’s legendary pocket watches: the 1A quality.

To this very day, the diamond endstone remains an unmistakable sign that stands for the exclusivity and refinement of a timepiece originating from the Saxon manufactory. In the noble Lange tourbillons of the new era, both bearings of the intricate rotating cage are capped by a dia-mond endstone. As was the case in earlier times, the most precious of all precious stones is not only a decorative element but also serves an important functional purpose today.
