The heart of the El Primero beats at a rate of 36'000 vibrations per hour, meaning 864'000 a day or 315'360'000 beats per year one vibration corresponds to the position of the lever as it swings to and fro, making the alternating "tick" and "tock" sounds. As there are 3'600 seconds in an hour (60 seconds times 60 minutes), and since El Primero beats at a frequency of 36'000 vibrations per hour, the hands actually thus make 10 jumps per second, thereby marking off tenths of a second.

Et la lemania de gousset , rattrapante au dixiéme de seconde et où on lit réélement le 10 éme( de 1941 et ayant été commandé par la marine soviétique , que je posséde en état impécable et rempli à ras bord ! ) contrairement à cette zenith qui demande quelque effort .

Because it's a secret business making process. Even Jaeger LeCoultre does have a movie as a making process introduction on its website, no way so why Zenith would have ?
