Patek Philippe 5520P-001

Alarm Travel Time

Friday, 11 June 2021

Wind it. Set the alarm. Wait. Then hear it — a mechanical hammer striking a gong inside the case, producing an audible chime at the time you chose. The 5520P is the only alarm in Patek's current catalogue, and the experience of using it cannot be replicated by any photograph, spec sheet, or review. You have to hold it to understand.

Collector's Note

The only mechanical alarm in Patek's current catalogue. The 5520P chimes using a hammer striking a gong — a complication so rare that most collectors never encounter one in person. It adds a functional dimension (an audible alarm, wound and set mechanically) that no other piece in the collection provides.
