Dominant Case | Bold Lines, Rugged Power

The 46mm diameter case is a hallmark of the Big Pilot series. ZF’s version builds on this foundation with a stainless steel case that exudes a strong, masculine presence. Through multiple polishing and brushing processes, the case achieves both striking visuals and a smooth, refined touch.

A highlight is the lug design: crafted with a subtle curve to fit the wrist naturally and comfortably, it demonstrates ZF’s attention to ergonomic detail.

Classic Dial | Minimalist Layout, Functional First

The dial carries IWC’s signature “cockpit instrument” aesthetic—a large black background paired with bold white numerals and hands ensures easy readability. The watch features a three-hand display (hours, minutes, seconds) along with a date window at 3 o’clock and a power reserve indicator, offering both practicality and visual appeal.

Both the hour markers and hands are coated with luminous material, ensuring clear time reading in all lighting conditions—a nod to its aviation roots.

Reproduced Movement | The Heart of the Original, Faithfully Recreated

ZF utilizes a self-developed replica of the Cal.51111 movement, with up to 90% visual similarity to the original and 100% functional alignment. It features a long power reserve and reliable timekeeping, showcased through the transparent case back, revealing its intricate mechanics.

From the balance wheel to the beveled gear bridges, every detail is finely crafted—ZF ensures it not only looks right but performs precisely.
