Ok, so here’s another masterpiece from my collection. For sale is the I have another piece incoming, so, as much as I love this one, it has to go. Use your chance to snatch one of the most legendary pilot’s watches ever created: the IWC Doppelchronograph Ref. 3713. Introduced in the 1990s and designed by the renowned Richard Habring, this timepiece marked a milestone in chronograph innovation by bringing the rattrapante (split-seconds) complication to a durable, tool-watch format at an unprecedented value. You can read more about the watch is this fine Fratello article https://www.fratellowatches.com/iwc-doppelchronograph-ref-3713-a-watch-thats-double-the-fun-for-those-who-dare/#gref Housed in a 42mm stainless steel case with military-inspired styling, the Ref. 3713 blends functionality, heritage, and mechanical mastery. The matte black dial offers superb legibility with bold Arabic numerals, luminous hands, and the unmistakable tri-counter chronograph layout – a nod to IWC’s dedication to aviation-ready design. What sets the Doppelchronograph apart is its in-house-developed split-seconds mechanism built atop the reliable Valjoux 7750 base. With this feature, you can time two events simultaneously – a complication rarely seen in watches at this price level and a technical feat that cemented IWC’s place in the pantheon of chronograph innovators. Now discontinued, the IWC Doppelchronograph 3713 has become a grail-worthy piece for collectors, especially those seeking the pre-ceramic era of functional, over-engineered pilot’s watches that put IWC on the modern map. Key Features: * Reference: IWC 3713 (Pilot’s Doppelchronograph) * Movement: IWC-modified Valjoux 7750 with in-house split-seconds module * Case Size: 42mm stainless steel * Dial: Matte black with white Arabic numerals and luminous hands * Crystal: Sapphire, anti-reflective coating * Complications: Split-seconds chronograph (rattrapante), day-date display * Water Resistance: 60m * Status: Discontinued – Collectible and increasingly rare Whether you're a fan of aviation history, high-complication watches, or simply want a chronograph with real pedigree, the IWC Doppelchronograph Ref. 3713 delivers both tool-watch utility and technical sophistication in a package that stands the test of time. This particular example is in very good, I’d say excellent condition, with no dents or deep scratches. The crystal and dial are perfectly clean, showing no blemishes or marks. Only minimal hairline swirls are present on the case and caseback, visible only under close inspection – fully in line with careful wear. Importantly, the watch was serviced by IWC official watchmakers just a few years ago, and it comes with documented proof of service. It runs flawlessly, with all chronograph functions – including the split-seconds mechanism – performing exactly as they should: crisp, responsive, and perfectly resetting. This sale includes the watch only on a leather strap with an IWC deployant clasp, plus an additional strap for your convenience. It is being offered as watch only, without original box or papers beyond the official service documentation. Price is $4,250 USD shipped CONUS. I’m in Canada, so Canadian buyers welcome.
