Pilot Doppelchronograph 3713

The IWC Pilot Doppelchronograph 3713 is a landmark in the world of mechanical chronographs, introducing split-seconds (rattrapante) functionality to the brand’s pilot lineup in the 1990s. Developed under the guidance of Kurt Klaus, this model elevated IWC’s tool watch pedigree by offering a complication typically reserved for high horology, all in a no-nonsense, legible pilot format. Collectors value the 3713 for its direct lineage from the original Doppelchronograph 3711, but with an updated, more wearable 42mm case and improved movement reliability.

Reference 3713 is powered by IWC’s modified Valjoux 7750-based Caliber 79230, featuring the signature split-seconds mechanism. Early examples showcase tritium dials (noted by “T SWISS T” at 6 o’clock), while later pieces use Luminova—this detail affects both collectibility and price, with tritium models often commanding a premium. The 3713 is water resistant to 60 meters, making it practical for daily wear, and the anti-magnetic soft iron inner case is a hallmark of IWC’s commitment to functional pilot’s watches.

When evaluating a 3713, dial condition and completeness (original box, papers, and bracelet/strap) are key value drivers. Variants include the standard black dial and the rarer “Flieger” dial with contrasting white hands and markers. Service history is important, as the rattrapante mechanism requires specialized maintenance—documentation from IWC or a recognized specialist adds confidence. This model’s production ended in the mid-2000s, so examples with unpolished cases and crisp engravings are especially sought after.
