The Group C era of endurance racing, which covered the early '80s to the early '90s, saw the evolution of race cars from primarily analog machines to digitized beasts. To celebrate the era, Autodromo offers up the Group C Digital Chronograph. Its 36mm stainless steel case — available in brushed or yellow cerakote — holds a seemingly simple backlit black and white LCD screen underneath a chamfered sapphire crystal. In addition to displaying the time and date, it can also time laps and serve as an alarm, with controls in the form of bright yellow pushers on the sides. Water resistant to 30 meters, both variants arrive on a reversible FKM rubber strap.
