The **Nautilus Perpetual Calendar Ref. 5740** is a wristwatch by **Patek Philippe**.

The first [[Grand Complication]] in the Nautilus collection (2018), this [[white gold]] [[perpetual calendar]] features an original blend of sportiness and technical sophistication. Thanks to the presence of the famous [[ultra-thin]] [[self-winding]] Caliber 240 Q, the case retains the exceptional slimness that makes it the thinnest Patek Philippe perpetual calendar.
