This watch also brings a first to the Patek lineup of calendar watches — the weekly calendar. This complication tracks which number week it is and uses a pointer-hand to indicate the number. In addition to that, the watch tracks the day and date. Patek claims this weekly calendar could be useful to the modern businessman, but let’s be honest, you’re not going to buy this because you need to be reminded when Q1 becomes Q2. You’re buying this watch because it’s cool. And there’s nothing wrong with that.
