This replica Pilots IW501002 46mm belongs to the Big Pilot’s Watch family, the largest and most visually commanding series within IWC’s aviation range. At 46mm the IW501002 fills the wrist completely, and the oversized conical crown was originally designed to be operated while wearing flight gloves. The Big Pilot format dates back to wartime Beobachtungsuhr instruments, and the IW501002 continues that heritage with a power reserve display at three o’clock and a date window at six. The dark dial, bold Arabic numerals, and propeller-shaped seconds hand tie every detail back to cockpit-era aviation.

Build Details

• Case diameter: 46mm
• Case material: stainless steel
• Dial: blue with luminous Arabic numerals
• Crystal: domed sapphire
• Functions: power reserve indicator, date
• Movement: automatic with 7-day power reserve
• Crown: oversized conical with engraving

The 7-day power reserve is one of the defining features of the Big Pilot platform. Most automatic watches deliver 40-70 hours; the IW501002 stretches that to a genuine 168 hours, while this clone build delivers 48-60 hours. That week-long reserve means the watch keeps running through an entire work week off the wrist without stopping.

What Collectors Notice

Big Pilot references have become a collector category of their own. The IW501002 represents the generation that introduced the power reserve indicator at three o’clock, replacing the clean dial of earlier references like the IW500401. That addition divides opinion among enthusiasts: some prefer the cleaner look, others value the functional information. The Blue Angels IW389008 chronograph offers an alternative path for big-case pilot watches, trading the seven-day reserve for timing capability. Both anchor the larger end of the Pilots collection.

This vs Other Versions

The IW501002 occupies a specific niche: maximum case size, maximum power reserve, minimum complications. No chronograph, no GMT, just hours, minutes, seconds, date, and power reserve. That deliberate simplicity is what separates the Big Pilot from the more complicated chronograph variants. This replica Pilots IW501002 46mm delivers that oversized instrument-watch experience for anyone drawn to the original Big Pilot proposition.

ZF Factory Build Quality

Le Petit Prince editions turn on a single colour, and this one carries it across a 46mm dial where any unevenness has nowhere to hide. IWC’s midnight blue has to stay deep in shade and open only under direct light — too light and it reads navy, too bright and it loses the night-sky reference the series is built on. ZF Factory leads the Big Pilot line and prints this dial to hold its depth edge to edge rather than lightening toward the centre. The conical crown is machined solid, and the clone 52110 drives a working power reserve indicator. Our Big Pilot guide covers the line in full.

Saint-Exupéry and the Blue

Antoine de Saint-Exupéry flew mail routes over the Sahara and the Andes before writing Le Petit Prince in 1943. IWC has run editions in his name since 2013, always in blue, with a caseback engraving of the Little Prince on his asteroid. The colour references the night skies he wrote about flying through.

Frequently Asked Questions

What dial colour is the IW501002?

Midnight blue. It is the Le Petit Prince edition, and blue is the signature colour of that series — the standard IW501001 is the black-dial reference. Listings describing this reference with a white dial have it wrong.

Is the movement automatic or hand-wound?

Automatic. The Cal. 52110 uses Pellaton winding with twin barrels for seven days of reserve. The hand-wound 51111 belongs to older Big Pilot references.

What is engraved on the caseback?

The Little Prince standing on his asteroid, the mark IWC uses across the Saint-Exupéry editions. It sits on a solid caseback rather than a sapphire window on this reference.

Which factory produces the best Le Petit Prince Big Pilot?

ZF Factory. The build is a colour problem before it is a mechanical one, and ZF holds the midnight blue depth across a 46mm dial where lesser printing lightens toward the centre.
