IW3577-01

The 2025 Big Pilot’s Watch Shock Absorber Tourbillon Skeleton XPL IW3577-01 by IWC Schaffhausen integrates advanced horological engineering with specialized materials designed for enhanced durability. This watch incorporates the patented SPRIN-g PROTECT shock absorber system, first introduced in 2021, marking its first integration with a tourbillon movement. The system employs a cantilever spring that suspends and cushions the movement within the case, effectively minimizing potential damage from shocks. At the heart of the watch is the IWC-manufactured caliber 82915, an automatic movement featuring a flying minute tourbillon. Extensive modifications were required to adapt the SPRIN-g PROTECT system to this movement, including recalculating and redesigning the spring structure using advanced simulations to accommodate the dimensions and weight of the tourbillon assembly. Through rigorous testing, the system demonstrated the ability to withstand accelerations exceeding 10,000 g, a per...
