1990 IWC Porsche Design Chronograph (Ref. IW3702)
The 1990 IWC Porsche Design Chronograph IW3702 is a vintage classic that perfectly embodies the partnership between IWC Schaffhausen and Porsche Design. Produced as the successor to the groundbreaking Titan Chronograph (Ref. 3700), this model carried forward the pioneering use of titanium in watchmaking while introducing a more robust movement and a timelessly functional design.
At its core, the IW3702 is powered by the Valjoux 7750 automatic chronograph movement — a legendary caliber celebrated for its durability, precision, and ease of service. The movement provides chronograph functionality, a day-date display, and a 42-hour power reserve, making it as practical as it is collectible. This reliability has ensured the watch’s continued appeal among enthusiasts and collectors looking for a vintage chronograph built to last.
The case is crafted entirely from lightweight titanium, a material that was revolutionary in the 1980s and 1990s and has since become a hallmark of modern tool watches. With a 42mm case size, the watch offers a commanding wrist presence while remaining extremely comfortable thanks to its relatively slim profile and integrated titanium bracelet. Porsche Design’s influence is clear in the bracelet’s seamless flow from case to wrist, emphasizing ergonomic comfort and sleek, industrial design.
The black dial follows a minimalist, highly legible layout - inspired by the Porsche 911 tachymeter design of that era. White contrasting indices, luminous hands, and a bold red chronograph seconds hand provide excellent readability in all lighting conditions. The tri-compax sub-dial arrangement reinforces its tool-watch functionality without cluttering the dial. This clean, purposeful aesthetic reflects both Porsche Design’s Bauhaus-inspired philosophy and IWC’s reputation for no-nonsense instrument watches.
Beyond its technical merits, the IW3702 holds an important place in watchmaking history. It symbolizes the era when Swiss horology and German industrial design merged to create something truly innovative. By pioneering titanium construction and integrated bracelet design, the IWC Porsche Design Chronograph paved the way for countless other sports chronographs that followed.
For collectors today, the IWC Porsche Design Chronograph IW3702 is more than just a watch — it is a piece of horological history. It represents the height of the IWC–Porsche collaboration and remains one of the most desirable vintage titanium chronographs available. Its understated design, technological innovation, and historical significance make it a sought-after model for anyone building a serious vintage chronograph collection.
Recently serviced and regulated, it is a perfect everyday watch for vintage lovers. Whether you are searching for a vintage IWC Porsche Design chronograph for sale, a collectible titanium sports watch, or simply a robust daily-wear vintage chronograph, the IW3702 continues to deliver on every front. Elegant yet purposeful, innovative yet timeless, this watch has rightly earned its reputation as a true classic.
