IWC Pilot’s Watch Double Chronograph 3770-01: Double Your Fun

The IWC Big Pilot’s Watch Double Chronograph 3778-01 is a standout model in the iconic IWC Pilot model line. IWC combines its in-house rattrapante (split seconds) chronograph system with the oversized vintage profile of the legendary Big Pilot Watch to create a high-horology hybrid that’s uniquely “Schaffhausen” in character.

Since the release of the first Big Pilot historical tribute models in the 2002, the oversized instrument-style aviator’s timepiece has become a staple of the IWC catalog and a flagship product for the Schaffhausen-based watchmaker.

IWC acknowledges that the most direct inspiration for the modern 3778-01 Big Pilot’s Watch Double Chronograph is the pioneering 1940 Type 52 TS C, a 55mm monster originally commissioned by the German Luftwaffe. At the time, the size of the watch was dictated by the functional necessities of the professional end-user; maximum legibility; a robust case to sit atop thick aviation gear, and a vast pocket watch movement to ensure utmost accuracy (smaller wristwatch movements continued to lag in this respect until the 1950s).

The dial of the IWC Big Pilot’s Watch 3778-01 is true to its inspiration in key respects. Each dial retains the look of an authentic aviation cockpit instrument; this is the strongest link to the 1940 original. However, the day-date window at three o’clock and the split-seconds chronograph function everyday practicality. Despite the size of the IWC Big Pilot, there is no impression of wasted space or extraneous detail; it achieves elegance in parallel with its functionality as a utility timepiece.

Inside the case, IWC’s caliber 79420 automatic rattrapante chronograph caliber provides durability and precision worthy of an aviation instrument. IWC starts with a bulletproof ETA/Valjoux 7750, and then the Schaffhausen split-second specialists customize the ebauche almost beyond recognition. By the time IWC adds its proprietary rattrapante chronograph architecture, a custom regulator with triovis micro-adjustment system, a unique IWC winding rotor, and IWC-specific fine finish to the Valjoux movement, the caliber effectively has become an in-house product.

This iconic IWC Big Pilot’s Watch Double Chronograph would be a knockout addition to any collection. With a stellar combination of historical authenticity, useful complications, and modern luxury watchmaking refinement, the IWC Big Pilot’s Watch Double Chronograph 3778-01 result is a must-see collector’s piece for fans of the IWC manufacture.
