History and Significance
The IWC Double Chronograph, or Doppelchronograph, is one of the more technically interesting chronographs to come out of the 1990s. Building on the Valjoux 7750 architecture, IWC engineered a split-seconds complication that allowed the wearer to time multiple events simultaneously. At the time, this was a serious mechanical achievement, especially considering the relative simplicity and robustness of the base movement.
The IW3713 represents an earlier execution of this concept, housed in a clean, instrument-style case with strong pilot watch influences. The dial layout is highly legible despite the added complexity of the split-seconds function, which is not always easy to achieve. Large Arabic numerals, bold hands, and a clear day-date display make it practical, while the additional pusher at 10 o’clock signals that there is more going on beneath the surface.
What sets this example apart is the early tritium dial. Over time, these dials develop a softer, warmer tone that contrasts nicely against the otherwise utilitarian design. The evenly aged lume across the markers adds a level of character that later luminova examples simply do not have, giving the watch a more collected feel without losing its tool-watch identity.
Writer’s Thoughts
The split-second function adds a level of interaction that most chronographs lack, making the watch more engaging over time. The tritium dial does a lot here. It softens what could otherwise feel like a very technical, almost sterile design. It’s also just a solid daily option for someone who wants a chronograph that’s a bit different but still practical.
