Video: Zenith El Primero Movement
Check out the unique and impressive movement of the Zenith El Primero. While the large second hand on most chronographs counts one second at a time, on the El Primer, the large center second hand registers time in 1/10 of a second increments by taking 10 seconds to make a complete rotation and then dividing those 10 seconds up into 1/10th increments. Talk about smooth!
