1990s IWC Doppelchronograph 'Split Second' (Ref. 3713)

Founded more than 150 years ago—by an American man named Florentine Ariosto Jones—the International Watch Company has grown to become one of the most recognizable Swiss watch brands on the planet. The brand has a long history of creating purpose built timepieces, especially those built for pilots. In fact, it’s arguably what IWC is best known for. 

This ref. 3713 “Doppelchronograph”, or Double Chronograph, was first introduced by IWC in the '90s with a design language based on the original Mark XI. The watch features the robust and accurate Valjoux 7750 as its base movement, but has an innovative split-seconds chronograph added to it. This allows users to time two events at once—or multiple parts of a single event—as the chronograph seconds hand splits at the push of a button (note the extra pusher positioned at 10 o'clock). 

Aside from the incredible movement, this is a quintessential IWC pilot's watch through and through—matte black dial, white Arabic numerals with lumed markers at 3, 6 and 9 o'clock, and a lumed arrow marker at 12 o'clock—and a timeless classic at the same time.
