Pay close attention to this video or you'll miss Tag Heuer's new Mikrotimer Flying 1000 in action. The new concept watch is the most accurate mechanical chronograph ever.
The Mikrotimer Flying 1000 measures time accurately down to 1/1000th of a second. That's so fast that at first glance you might not even catch what's going on in the video. After the chronograph starts, the yellow hand starts ticking out the time every .001 seconds. The hand spins so fast that your eyes can barely glean its motion -- until the chronograph is stopped 10 seconds later and you realise what was going on all along. [Hodkinke and TAG Heuer via OhGizmo]
