Catalogue Note

Accompanied by an Extract from the Vacheron Constantin Archives confirming date of manufacture in 1930.

In 1925 the watchmaker Robert Cart created a unique complication which he called, the ‘Jumping Hour’ or ‘chronoscope,’ under patent number 130191. This was a brilliant system of jumping hours and wandering minute indication.

Breguet and Vacheron & Constantin were particularly keen to adopt the mechanism, of which there were two types. Breguet tended to use the first example with the wandering hours, and Vacheron the second type with the fixed indication aperture at 12, as we see in the present watch.

This example is a particularly fine and unusual one as it features not only a two-tone case in beautiful condition, but also a triangular tipped revolving ruby minute indicator
