What you are looking at right now is perhaps one of the most complicated and beautiful clocks ever made. It is named Computus Easter Clock, and it was created by Konstantin Chaykin, a renowned Russian watchmaker. It includes no less than 1,375 individual parts and measures about 23.5 inches in height. As its name suggests, it was created to detect the moving date of the Eastern Orthodox Easter, which is usually quite difficult to calculate as it depends on several factors such as solar cycles, lunar cycles, the solar correction and more.
The watch was created using high-quality materials such as brass, steel, silver, marble, duralumin, gold, lapis lazuli and glass, and the case was inspired in its design by the St. Isaac Cathedral located in St. Petersburg, Russia. The church’s decorations, including the image of Archangel Michael and the “Risen Christ” were reproduced with incredible attention to detail using jade, jasper, lapis lazuli, sandstone and violan. As for the movement, it required more than 10,000 hours of hard work in order to be complete, and it comprises 68 bearings, 16 jewels, a power reserve of 10 days, 16 time-telling indications and a one-minute tourbillion that operates at a frequency of 18,000 vibrations per hour.
