This worthy descendant of the Chronomaster lineage features a sleek, robust and beautifully proportioned steel case measuring 41 mm wide with pump-style pushers. It is driven by the new high-frequency El Primero 3600 calibre offering greater performance and precision than ever. Endowed with a 60-hour power reserve, the mechanism and its striking architecture can be admired through the sapphire display back revealing a blue column wheel and open rotor marked with the five-pointed Zenith star. The new Chronomaster Sport is the only watch to feature a 1/10thof a second display etched directly on its polished and graduated black ceramic bezel. The exceptional legibility ensured by contrast effects continues on the particularly refined black or white dial bearing the signature El Primero tri-colour chronograph counters in blue, anthracite and light grey, each graduated to 60 for intuitive and readings. This distinctive new comer is teamed with an eminently comfortable integrated steel bracelet or a textured cordura-effect rubber strap option, secured by a steel folding clasp.
