ZENITH BRINGS BACK THE FIRST EL PRIMERO WATCH WITH A GRADIENT DIAL FROM 1969: CHRONOMASTER REVIVAL A385.

A legend is born again: Zenith is bringing back one of the earliest and most emblematic El Primero-equipped chronographs from the earliest days of the revolutionary calibre in the form of a Chronomaster Revival model.

The A385 made headlines back in 1970, when it took part in Zenith’s “Operation Sky”. This extreme test consisted of strapping the watch to an Air France Boeing 707’s landing gear on a flight from Paris to New York to test its resistance to external aggressions such as drastic temperature fluctuations, wind force and changing air pressure. Upon landing, the watch was still functioning perfectly. This daring feat was a testament to the confidence those who had tirelessly worked on the El Primero calibre held, as well as tangible proof that a mechanical movement was superior to the nascent quartz movements of the time, which couldn’t have stood the temperature differences endured by the watch during the flight.

After over 50 years, the time has come for the A385 to make its return in the form of a Chronomaster Revival model. Far more than just a vintage-inspired creation, the Chronomaster Revival A385 is an actual reproduction of the original model from 1969 in an exercise of “reverse engineering” by the Manufacture. Using the original blueprints and production plans, each part of the A385’s 37mm tonneau-shaped stainless steel case, including the pump-style pushers, is faithful to the original 1969 model. The only differences, are the domed sapphire crystal instead of an acrylic glass and the display back instead of the closed solid steel case back, offering an unobstructed view of the El Primero 400 chronograph movement.
