How do I set the date on a Patek Philippe Nautilus?

To set the date on a Patek Philippe Nautilus, locate the small push buttons on the outside of the case and press them using a small tool that won’t scratch the metal, such as a toothpick. Each button controls a different parameter such as month and day. For more specific settings instructions, consult the brand’s website.
