Successor to the 52110, the Calibre 59210 shares the same architecture but introduces a 7-day, Pellchron-driven power reserve indicator, replacing the traditional subdial. This novel feature, along with the 52110, demonstrates IWC's continuous pursuit of advanced movement technology and design.

Calibre 79320

Introduced in 2019, the 79320 is a self-winding movement based on the 99320 caliber but modified for use in the Big Pilot's Watch. It features an 8-day power reserve, displayed on a subdial at the 3 o'clock position, and a Pellchron system that constantly adjusts the wound rate to optimize efficiency.

The 79320 embodies IWC's commitment to combining traditional watchmaking with cutting-edge technology. The movement's oscillating mass, for example, borrows its design from a vintage airplane propeller, further solidifying the connection between the Big Pilot's Watch and its aviation roots.

The Big Pilot's Watch is more than just a timepiece; it's an enduring testament to IWC's commitment to craftsmanship, innovation, and classic design.
