Other types of modern-day chronographs are the "automatic chronograph" and the "digital chronograph". Heuer's first automatic chronographs were the Autavia, Carrera, and Monaco. Common complications include date or day-of-the-week indicators, alarms, chronographs (stopwatches), and automatic winding mechanisms. The following year, Breitling started making chronographs for Bentley Motors. These first automatic chronographs were labelled "Chrono-matic". Bullhead watches are generally, but not exclusively, chronographs. In the mid-1970s, Heuer introduced a series of chronographs powered by the Lemania 5100 movement. The earliest of Heuer's Cal 11 chronographs (from 1969) were named "Chrono-Matic". Some of these watches, such as chronographs, contain more than one stepping motor. Specialized chronographs are used by deep sea and scuba divers. More modern uses of chronographs involve piloting airplanes, car racing, diving and submarine maneuvering. All chronographs tested were mechanical hand-wound models. By 1948, the company was focusing on sporty chronographs that prominently displayed the current date. One of these chronographs was worn by Formula One Champion Mario Andretti. The original chronographs that Rieussec invented were called tape chronographs.
