Designed by Verger FrÃ¨res, the 1930 Vacheron Constantin "Montre Ã Volets" shutter watches feature dials concealed by hinged panels in 18k Art Deco cases. (Pictured above left.) Recent auctions have fetched prices upwards of $20,000 each. â€œJalousie," the re-introduction of the shutter watch by Vacheron Constantin in the 90's uses a Cabochon sapphire as a switch to open the shutters revealing the dial and brings in less than half of what the originals go for at auction.
