Vacheron Constantin Patrimony Traditionelle 14 Day Tourbillon Openworked

Second up for the 2014 Vacheron Constantin lineup is this Patrimony Traditionelle 14 Day Tourbillon Openworked.  As noted in my reveal of the new Malte Tourbillon Openworked a few minutes ago, Vacheron is this year putting on full display its exceptional talents in the arts of skeletonization and engraving.   These watches are breathtakingly gorgeous.  Particularly if you are a lover of combined skeleton + engraving work as I am.

Like the standard PT 14-Day tourbillon, there is also a Power Reserve display situated near 12 o’clock on the dial.  In addition to its beauty, keep in mind this watch has an impressive 14-day power reserve.   The Patrimony Traditionnelle 14-day tourbillon openworked comprises four barrels stacked in pairs in the upper part of the movement, making it more ‘crowded’ than the lower part.

Compared with the solid base movement, a single 2260 SQ calibre requires 10 additional hours of chamfering and hand-drawing, as well as 40 extra hours of engraving.  By the way, the “SQ” refers to “squelette” which is the French word for “skeleton”.

Note the different “flavor” of the engraving on this caliber 2260 as compared to the much more angular and geometric patterns on the caliber 2790 found in the Malte Tourbillon Openworked.
