HEUER (and now Tag-HEUER) designs stopwatches for various purposes to help many professionals in their activities. Most famous are sport stopwatches and especially sport cars stopwatches. The ref. 408.417 is one of them. It’s a tachymeter with flyback function (which is activated by the right pusher). The outside redscale give the average speed to cover 1 kilometer or 1 mile. If the driver covers 1 kilometer in 30 seconds, it means its average speed was 120 km per hour. That’s a pretty trivial example, easy to calculate, but for other value, it gives instantly the speed without calculating.
