Cyrus Watch Kambys Titanium 529.001.C. The name Kambys comes from Cambyses which was the name of Cyrus The Greats son and successor. The first letter has been changed to match the first letter of the other collection, Kuros and Klepcys. The K stands for King, a reminder of Cyrus The Great. Cyrus has dared to launch a timepiece with manual twin barrel winding and a seven-day power reserve. The movement is a 100 percent in house manufacture movement, created under the aegis of renowned, award winning Swiss watchmaker Jean Francois Mojon. The design of the watch is not round like most watches, but instead the tonneau shaped modified to fit most wrists.
