More eyes were on Vacheron than had been in a while and it even resulted in a boom for the vintage 222 market (though Vacheron as a whole still struggles on the vintage market). Brad Pitt was spotted wearing a new gold 222 and then, later, a vintage one in steel (even link though he was still, at the time, a Breitling ambassador). A link likely unique white gold link 222 sold at Phillips Geneva for CHF 571,500 (the seventh most expensive Vacheron wristwatch ever sold at auction).
