The IWC Pilot's Watch Doppelchronograph ref. 3713 was in production from around 1996 to 2005. It's the second pilot's watch from IWC to have a split-second chronograph feature. You could get it in stainless steel, yellow gold, or platinum, and it came in a variety of dials. The stainless steel version had a choice of a strap or bracelet, while the platinum version only had five pieces made with a bracelet. Starting in 2003, the 3713 only came with Spitfire-style dials. The specific model IW3713-38 has a stainless steel case and a black 'Spitfire' dial.
