This Vacheron Constantin Chronomètre Royal Ref. 6694, from the 1960s, stands out as a rare model. The example we have, crafted in 18k white gold, is especially sought-after since most Ref. 6694 were produced in 18k yellow gold.

The dial is all original with applied baton indices and a diamond-set Maltese Cross. Its 35mm-wide case features distinctive wing-shaped lugs (nicknamed “Batman” by some collectors) and a screw-back. The movement is a beautifully finished Calibre 1072, which has an 18k gold rotor and is Vacheron's first self-winding movement to receive COSC certification.
