By the time they needed it the most, the Porsche team's racing chronograph had seen a lot of action. But was an important design for Omega. Powered by the high-beat caliber 1131, these split-second chronographs were developed in 1966, so that two years later, Omega could send 45 units to the Summer Olympics in Mexico. As , Omega has been the Games' official timing partner since 1932, and while Mexico City got 45 individually marked black-dialed Olympic stopwatches for 1968, the Swiss also sold a few to high profile athletes, including John Partridge, a member of the British Cycling Federation. Interestingly, the 1977 Porsche team's cherished chronograph is an even rarer, white-dialed variant.
As the Omega would prove, during qualifying, everything seemed fine with the 936/77 Spyder.
Driven by Jacky Ickx, Jürgen Barth and Hurley Haywood, that continued to be the case up until the 24th hour, when 45 minutes before the finish on Sunday, the single-turbo flat-six blew a cylinder. Smoking badly, Jürgen Barth had to pit.
Twelve minutes before the end, Barth fired up his now five-cylinder Porsche. They were still in the lead. The regulations said the car had to complete its pit lap and do a final one at speed without crossing the line before 4 p.m., as making that error would have started a new lap.
To make sure Jürgen Barth wouldn't hand over the victory to the Renault-powered Mirage GR8 by losing sight of the time, to fix the Omega on his steering wheel. Ten minutes later, the Porsche 936 secured its second Le Mans victory.
