In 2008, a small factory produced a clone of the IWC Big Pilot, which had significant differences from the genuine watch in both appearance and movement, including a faux power reserve. Seven years later, Z factory revisited this model, enhancing the dial and movement construction, and introducing a real power reserve that increased from 42 to 12 hours. The IWC Big Pilot is one of the brand’s most iconic series, known for its high price, making a precise 1:1 replica a dream for many enthusiasts. This review focuses on the Big Pilot IW500901 replica, a timepiece with flawless functionality and a movement that closely mirrors the original.
The watch features a large 47mm brushed case, designed similarly to dress watches, with a dial that ensures excellent readability. The side profile reveals the superior craftsmanship of this 1:1 replica compared to cheaper alternatives. The case is meticulously polished, particularly the bezel, which boasts a mirror-like silver edge. The streamlined design ensures a comfortable fit on the wrist. Photos demonstrate the sapphire crystal’s anti-reflective coating, which enhances dial clarity under sunlight, making the crystal appear almost invisible.
The black dial is highly legible, thanks to large white hour markers and hands. Numerals are present except at 3, 6, 9, and 12 o’clock. The design adheres to military standards, not only due to the black-and-white contrast but also because of the luminescent material applied to key markers and hands, ensuring visibility in low light. The onion-shaped crown, a signature feature of the Big Pilot, is easy to operate and fits seamlessly with the case, providing 50-meter water resistance.
The movement is a clone of the IWC 51111 automatic, featuring a functional power reserve—a significant upgrade from earlier IWC Big Pilot replicas. The working power reserve indicator reflects the advancements in replica watch manufacturing. Opening the case back reveals the meticulous craftsmanship justifying its higher price point.
