While the design of this watch is certainly the selling point - one can't forget that the caliber 1003 inside is also something of historical importance. Made entirely of gold, the caliber 1003 is the world's thinnest mechanical movement at 1.64mm thick - and though it was originally introduced in the 1950s, it is now finished to even higher standards and has a power reserve of 30 hours, despite its miniscule size - really an amazing feat of watchmaking. The entire watch meets the requirements set forth for the Geneva Seal, of course.

Vacheron Constantin will also offer a 40 piece limited edition of the 1972 Prestige with a high-contrast silver dial and black strap - available only at select Vacheron boutiques. The price for this special new watch will be $40,000. You can read more about the new Paris boutique and the Prestige 1972 right here.
