The IWC Pilot's Watch Doppelchronograph ref. 3713 was produced between 1996 and 2005. This was the second of IWC's pilot's watches to have a split-second chronograph. It came in stainless steel, yellow gold, or platinum, with different dial options and day-discs in various languages (though not always shown in our pictures). The stainless steel version could be worn with a strap or bracelet, while only five pieces of the platinum version were made with a bracelet. Starting in 2003, the 3713 could only be found with Spitfire-style dials. The specific model IW3713-08 features a stainless steel case and a black dial.
