Konstantin Chaykin Decalogue Luah Shana (with engraving)

On the eve of Hanukkah, Konstantin Chaykin presents the updated Decalogue Luah Shana watch. The new unusual design created in a single copy.

Inspired by works of art of the Jewish people the author has updated their incredible handmade engraving. The majestic columns placed on the face of the watch, which offers a beautiful view of the central part of the watch, which includes: an indicator of hours and minutes, moon phases and lunar calendar.

The Decalogue Luah Shana Watch is Hebrew in both design and in how time is indicated. The hands move from right to left, a reminder of how time was indicated on the famous tower clock on the Old Town Hall in the Josefov, the old Jewish quarter of Prague. The Decalogue Luah Shana also uses Hebrew letters instead of numerals on the dial, which are read right to left as well.

The artists who designed the Decalogue Luah Shana Watch turned to classic Hebrew artwork and design elements for inspiration. There are columns on the dial which represent the famous columns of the First Temple, the Temple of Solomon. These majestic columns are described in the Tanakh by Melachem.

King Solomon commanded to build two copper columns placed on either side of the main entrance of the Temple. Both were 9 meters tall: the right (south) column was named Jachin (‘He confirms’ in ancient Hebrew) and the left one (north side) was named Boaz (“The strength is in Him”). The columns were cast by master Hiram from Tyre. Hebrew letters are used to mark the hours on the Decalogue Watch and the hours progress from right to left as is standard for the Hebrew system.

Each letter has a numerical value ranging from 1 to 12 according to gematria from the Kabbalah. Therefore, the hands on the Decalogue Watch also move ‘anti-clockwise’ as it were. This function is called the reverse system of hand movement. Konstantin invented this function for the Decalogue and Decalogue Rega Watches and has patented it.

The large lunar phase indicator is a stylized replica of the stone tablets on which the Ten Commandments, the Decalogue, were carved in ancient Aramaic by God and given to Moses on Mt. Sinai on the fiftieth day after the Exodus of the Jews from Egypt. There is an indicator of lunar days underneath. The lunar phase indicator is vital for in this watch: it allows the owner to calculate Jewish holidays. This indicator makes it easy to track the beginning and end of lunar months.

The proprietary K 01-0 caliber is visible through the sapphire glass on the back of the case. The Luah Shana Watch is a fine example of elegant watchmaking art: the bridges are decorated with ‘cotes de Geneve’, gold chatons support the jewels, and the facings on barrel wheel are perfectly polished. The Hebrew nature of the watch is reiterated by the Star of David engraved on the barrel wheel and decorated with blue enamel.
