Calatrava Pilot Travel Time Alarm 5520 Platinum / Black

In Context

At 42.2 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.6 mm thick it is about average for a modern wristwatch. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 45 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

5520P-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a platinum case. Introduced in 2019.

Mechanical self-winding movement with dual time zone mechanism indicating local and home time and local and home day/night indication in apertures.
