Zenith Chronomaster Sport

The Chronomaster Sport measures a tenth of a second, and the bezel is graduated to show it. That is possible because the El Primero 3600 beats at 5 Hz — 36,000 vibrations an hour — the frequency Zenith reached in 1969 and nobody has surpassed in a series chronograph. In titanium at 41mm the watch is noticeably lighter than its steel sibling, and the central chronograph hand sweeps a full turn every ten seconds.
