D. Dornblueth & Sohn caliber 99.1
After some time, the two master watchmakers found that the caliber 99.0 with its small subsidiary second needed a somewhat more harmonic face. The pure design of the Cal. 99.0 was supposed to be continued nevertheless in the dial. Different issues had been in consideration, but the increasing of the small “second” played the favorite role. With the help of a long-standing friend of the family the new face of Cal. 99.1 was born.
