Clock – Collection: Hijra

Clock - Lunar2

Collection Description:

Hijra (translated from Arabic) means migration and emigration. The term is used to denote the Islamic era established by the second caliph of the Arab caliphate Omar I in 638 of the Common Era in honour of the migration of the Prophet Mohammad from Mecca to Yasrib (Medina). This event is considered as key to the history of the emergence of Islam. 17 years after the great migration, caliph Omar I made it the foundation of the Islamic calendar, taking Friday, 16 July 622 – the day the Prophet Mohammad left Mecca – as the first day of the new era. It is a lunar calendar, meaning that the periods are calculated according to the changes in the phases of the moon. It thus does not depend on the movement of the sun.

Technical Informations:

You will not be able to find a timepiece even close to this one at any other Manufacture. The design of this clock contains an invention patented by Konstantin Chaykin (patent no. 2308748): a device that displays the months and dates of the Islamic calendar. The case of the clock is made from precious species of wood and represents a stylised mihrab into which the unique clock movement is placed. Its sides are held together by an openwork lattice with ornate floral decor in the tradition of mosques.

Over 350 manually polished and smoothed parts are assembled in a single movement, thereby demonstrating the unsurpassed quality of manual workmanship. The Maltese cross provides constancy in the winding torque of the spring, thereby enhancing the accuracy of the clock’s operation. Meanwhile, eight precision ball bearings ensure the movement’s axes work for hundreds of years.

The Lunar Hijra contains seven complications: 1. a one-minute tourbillon, completing 18,000 half-oscillations per hour, 2. a moon-phase display, 3. a month display (Gregorian calendar), 4. a date display (Gregorian calendar), 5. a days-of-the-week display in Arabic, 6. a month display (Islamic lunar calendar) with a mechanism to adjust the duration of the lunar month, 7. a date display (Islamic lunar calendar).

The Lunar Hijra collection includes a basic model with a month and date display (Islamic lunar calendar), as well as a modified version of the clock featuring a retrograde month and date display (Islamic lunar calendar).
