Of course, inside Zenith is placing its El Primero high-frequency automatic chronograph with column wheel.Įchoing earlier Revival models, Zenith is reproducing the recently discovered dial within the 38mm case (with pump-style pushers) paying close attention to the blueprints of the original. This past week Zenith debuted the Chronomaster Revival Manufacture Edition, a production model Chronomaster cased in the El Primero A386 steel case and using the all-blue-subdial design on its dial. But instead of the grey, black and blue subdials, the discovered prototype featured three different shades of blue.Īnd while Zenith says it has no records of these blue tri-color dials, the watchmaker has determined that they were part of the original prototype dials for the El Primero A386 in 1969 featuring a 38mm steel case. There, amid piles of boxes, Zenith found another version of its now well-known Chronomaster tri-color dial.


As Zenith prepared for last year’s fiftieth anniversary celebration of El Primero, its premier automatic chronograph, the Le Locle watchmaker sifted again through the cache of tools and prototypes slated for destruction in 1975, but preserved at the time by the forward-thinking Charles Vermot.
