Rarity aside, the reference as a whole, and this example, are compelling in their own right for a few reasons. First, it’s powered by the Cal.  K1072/1 – the brand’s first movement to receive the Poinçon de Geneve seal. Second, this is effectively the first sports watch from Vacheron Constantin, in that it predates the 222. To wrap things up with a bang, shift your focus towards the dial on this example, which is white with black lacquered indices. Of all the Ref. 6782 dials, this variant and the gold tapisserie are said to be the rarest to have been fitted within yellow-gold cases. This means we’re talking about a rarity within a rarity, like Beethoven’s 5th, or a ’72 Dark Star.
