Konstantin Chaykin Decalogue Watch Available On James List

Konstantin Chaykin Decalogue Watch Available On James List Sales & Auctions

St. Petersburg based Russian watch maker Konstantin Chaykin is one of the independents that I watch closely. Their new watch for 2011 was the Lunokhod that I covered here. Though this Decalogue is a piece they released last year as a limited edition of 76 pieces. The watch is actually based on a large clock in Prague that also features Hebrew characters as the hour indicators. Like the clock, the watch tells the time with the hands going counter-clockwise.

This seemingly odd feature has to do with the Hebrew language, which is read right to left versus left to right. Therefore, to the left of 12 o’clock on the dial would be 1 o’clock versus 11 o’clock. Each of the Hebrew characters has a numeric property, so they do actually indicate 1-12 on the dial (just in the reverse of how most watches do). The result is a watch that basically indicates the time in the same, but reverse way as standard timepieces.

The name Decalogue is actually another term for the Ten Commandments – which obviously has religious significance in Judaism as well as other religions. Hebrew is based on Aramaic, and on the dial of the watch you’ll see Aramaic characters in addition to the Hebrew hour indicators. The piece also has the Star of David placed on it in three separate places. First as the subsidiary seconds dial, and then on the crown as well as engraved on the mainspring barrel on the movement. While the watch is clearly meant to be as an item of Judaica, it does not present itself as such in a cheesy way (well the Star of David seconds hand is debatable on that point). Actually, there is a version of the Decalogue watch called the Decalogue Rega that does not have the subsidiary seconds dial.

Inside the watch is an Konstantin Chaykin manufactured and designed caliber EVA01 manually wound movement. It is made with steel, brass, and other gold or platinum. The movement has a power reserve of 48 hours and features the time (indicated counter-clockwise) as well as the phase of the moon. This latter feature is appropriate because the Jewish calendar is a lunar versus solar calendar.

The Decalogue watch itself is 40mm wide in 18k white gold (also available in steel I believe). It is said to be also be made by Konstantin Chaykin. The bezel is designed to look a bit like a star with many (many) points. Crystals are sapphire and there is of course a display caseback. It is matched to an alligator strap.

As a collector’s item a watch like this will certainly have appeal to some people, and not others. The detail involved as a Jewish cultural watch is interesting, and I think that all people can appreciate the technicality and in-house made movement. Price is not entirely unreasonable at about $13,000 -$25,000, and you can see one available on James List here.

    Is there any reason you are showing some of the fugliest watches ever made? Is it to get them all out of the way at once before getting back to the Grand Seiko’s, JLC’s, ALS’s, and the like? This may be the cheesiest and most tasteless watch I have ever seen and I am including McDonald’s Hello Kitty timepieces sold with Happy Meals. As Indiana Jones said keep ones eyes shut and do look look directly at this watch. I am sure it may cause ones face to melt off from sheer force of kitsch as well as god’s wrath for buying such an abomination. Also isn’t there a commandment against taking the Lord’s name in vain and inscribing the Decalogue on an expensive piece of jewelry would probably be frowned upon.

    • Steve, we can tell you really like the watch. I might be able to get you a good deal on one 🙂

  • Dean Grant Baker

    @ Steve; Amen.
    would ultra orthodox Jews have to wear this strapped to their foreheads?

    Oi vey what a craptastic watch.

  • Ulysses

    It goes backwards. For no apparent reason. It has a silly smiling face edged in gold. On one of the models, the second-indices don’t even go all the way around. Itay Noy make nicer watches if you’re into the Hebrew theme. Not that last example you posted though – that was plain awful – but their website has some nice pieces. You’d have to be completely fakakta to want this thing. Still, it’s gold and it’s gaudy, so i’m almost certain rabbis everywhere will want one.

  • Eric

    Are there any watches that feature spinning crosses for the seconds hand? Instead of numbers on the dial it could have miracles 🙂

  • dshon

    I’ll refrain from commenting on the aesthetics- the previous posters have that well covered. But I’m surprised by a -10 to +15 sec / day accuracy range. This is well out of the range that any serious watch company would permit a high-end watch to run. Even those that don’t bother with COSC certifications usually utilize tighter standards. Any explanation?

  • David

    Ulysses… not quite “no apparent reason”. High above the street in Prague’s former Jewish community center, sits a clock whose face is different from all other public clocks in the world. Placed on the tower of the Jewish Town Hall, it was made in 1764 by Sebastian Landensberger, clockmaker to the royal court. After all, if the Hebrew language reads from right to left, then shouldn’t a Hebrew clock go opposite to the direction of all other clocks, right to left from a clock’s perspective?

    • David

      And yes, its numbers are in Hebrew letters, and the hands move counterclockwise! It seems “counterclockwise” is a relative term.

      • Ulysses

        It’s true that Hebrew reads from right to left but so do many other languages and yet they follow the Western convention, in non-literary uses, of being written left to right. I’m not saying one way is better than another, but the watch would probably have more appeal to a wider audience if it turned in the “usual” way. Then again, it wouldn’t really be a fitting tribute to that clock you mentioned if it were to do that.

    Look at traditional Jewish backwards wristwatch “Zman Avar” –
