The IWC Big Pilot’s Watch Tourbillon Le Petit Prince (ref. IW329502) combines technical prestige with poetic design, rendered here in Armor Gold – an exclusive alloy that offers increased hardness and warmer tonality than traditional red gold. The 43 mm case contrasts beautifully with the sunburst blue dial, an emblematic feature of the “Le Petit Prince” editions, enhanced by the spectacle of a flying tourbillon at 6 o’clock.

Launched in 2023, this reference is powered by the in-house calibre 82905, an automatic movement featuring a Pellaton winding system and hacking tourbillon with stop-seconds functionality. It delivers a power reserve of 80 hours and is regulated to ensure precision despite the airborne complexities of the escapement. The case maintains IWC’s signature utilitarian proportions while water-resistant to 100 m – a nod to the watch’s aviation roots.

As part of the limited “Le Petit Prince” lineup, this tourbillon edition elevates the Big Pilot into haute complication territory while preserving its legibility and ruggedness. The warm lustre of Armor Gold paired with a technically advanced tourbillon makes reference IW329502 one of the most refined – and rare – models in the modern Big Pilot family.
