May 10, 2007 - Marc Guten, Vacheron Constantin’s International Director, and Nicolas Deflers, Director of Vacheron Constantin Russia, presented a Malte Quantième Perpétuel Rétrogradant timepiece, created exclusively for Vacheron Constantin’s Moscow boutique, to a group of Russian collectors.

Manufactured in a very limited series of only five pieces in 5N 18K pink gold, this model has two exclusive features:

- An officer back which has been engraved on the outside with the Russian coat-of-arms, with its two-headed eagle. When the back is lifted, the very compact – 11 1/2 lignes for a thickness of 5.05 mm – Manufactory-made 1126QPR automatic mechanical movement can be admired through a sapphire crystal.

- A black dial whose surface, thanks to the texture of the finishing, absorbs rather than reflects the light and greatly improves legibility of the time. This is indicated by two facetted sword hands and 5N 18K pink gold applied hour-markers and Roman numerals.

This Perpetual Calendar timepiece also features a retrograde date. At the end of the last day of each month, its hand jumps back instantaneously to the first day of the following month and starts all over again. Well- proportioned with its 39 mm case and with its fan-shaped horns and a crown stamped with a stylised version of the Maltese Cross, this timepiece only needs to be set once a century! So it won’t need setting again until 2100!
