In 1993, IWC introduced the Ref. 3711, which came before the more well-known 3713. This particular model was the first of IWC's pilot's watches to have a split-second chronograph function. One notable difference between the 3711 and the 3713 is the domed glass on the former. The 3711 was available in stainless steel, yellow gold, and platinum, with a variety of options for the day wheel and alligator strap. The reference list includes 28 versions, with options for different dial colors and bracelet options for the stainless steel models.
