The IWC Pilot's Watch Doppelchronograph ref. 3713 was made from 1996 to 2005 and was the second of its kind with a split-second chronograph. It came in stainless steel, yellow gold, and platinum with different dial options, and some even had day-discs in different languages. However, not all of the pictures accurately show this feature. The stainless steel version could be worn with a strap or bracelet, while the platinum version only had five pieces available on the bracelet. After 2003, the 3713 was only sold with Spitfire-style dials. The reference IW3713-25 has a stainless steel case and a black dial.
