Zenith Chronomaster Sport 03.3100.3600/21.M3100 Watch for Men

With a black lacquered dial and three coloured counters, the Zenith Chronomaster Sport 03.3100.3600/21.M3100 is housed in a 41 mm stainless steel case topped by a black ceramic bezel. Inside is the automatic El Primero 3600, a chronograph calibre that reads elapsed time to 1/10th of a second. Kamal Watch Co. is an authorised retailer of Zenith watches.

Zenith built the Chronomaster Sport from details of its earlier chronographs, the tri-colour counters, pump-style pushers and a steel bracelet, and set them in a modern 41 mm case with a ceramic bezel. This version uses a black-lacquered dial and an integrated steel bracelet. Its El Primero 3600 has 311 components and 35 jewels and runs at 36,000 vibrations per hour, so the central chronograph hand sweeps the dial every 10 seconds; the reserve is about 60 hours. A domed sapphire crystal covers the dial, and the 13.6 mm case is water resistant to 10 ATM.
