ZENITH CHRONOMASTER OPEN
03.3300.3604/21.C822
The CHRONOMASTER Open showcases the inner workings of the El Primero movement through its dial. Designed in a sleek 39.5mm steel case, this model highlights a matte black dial with tricolour sub-dials and a transparent sub-dial for the running seconds, complemented by a black cordura-effect rubber strap. It is driven by the El Primero 3604 automatic chronograph movement, providing precise 1/10th of a second accuracy.
