The IWC Pilot's Watch Doppelchronograph ref. 3713 was produced between 1996 and 2005. It was the second of IWC's pilot's watches to have a split-second chronograph. You could choose from stainless steel, yellow gold, or platinum with different dials and day-discs in various languages. The stainless steel version had both a strap and bracelet option, while only five platinum pieces were made with a bracelet. After 2003, the watch was only available with Spitfire-style dials. The reference IW3713-19 has a sleek Stainless Steel case and a classic Black dial.
