Notes

Ref. 6087 is considered one of the most spectacular wristwatch chronographs of all time. Vacheron Constantin's technical designers named it for the shape of its lugs, in the form of ?cornes de vache?, which naturally evolved from teardrop or flared lugs. According to the Vacheron Constantin archives, a total of 36 examples of Reference 6087 were produced from 1954 to 1959. Of these, 26 examples were in yellow gold, 8 only in pink gold, and 2 in platinum, made on special order. Various types of dials were used for these watches: with telemetric scale; with tachometric scale; and without scale. Watches with mixed scales are extremely rare and this lot is only the second example to appear at auction. Antiquorum sold a similar watch with movement No. 470023 and case No. 351606 in its ?The Quarter Millennium of Vacheron Constantin? auction in Geneva on April 3, 2005, lot 152.
