This astonishing clock has been manually created from the first to the very last part, and is a unique timepiece. Its name 'Al-Biruni' was born when the style and philosophy of the clock were being developed, when Konstantin Chaykin was studying the theory and history of the Islamic calendar. Abu-r-Raikhan Biruni, or Al-Biruni, was the name of the greatest Eastern scholar from Khwarezm, who contributed enormously to the development of the science of calendars and chronology, and particularly the Islamic lunar calendar. The watchmaker decided to name this unique clock after this outstanding Muslim scholar to honour the great discoveries of the sages of medieval Asia, and to pay due respect to the greatly rich scientific and cultural heritage of the East.
While the entire clock is just 13 cm tall, the watchmaker was nonetheless able to masterfully fit additional complications into its miniature dimensions. The movement is equipped with date and month displays according to the Hijra lunar calendar, together with a tourbillon and moon-phase display.
The silver case reflects traditional architecture from Central Asia and is decorated with a fascinating mosaic composed of lapis lazuli, jasper, smalt and tiger's eye. It recalls the mosaics present in mosques and madrasas in Samarkand and Astana. The magnificent mother-of-pearl dial features gold-plated numbers written in Arabic, the language of the Prophet.
