This watch was the inspiration to the recent Zenith Chronograph Shadow Revival
Zenith, when announcing in 2020 its vintage-inspired Chronomaster Revival ‘Shadow’ watch, drew attention to an unusual and rare vintage timepiece from the brand’s museum collection: “The Chronomaster Revival Shadow mimics the look of an obscure Zenith chronograph prototype from the 1970s that featured a blackened case.”
The present example is one of the said ‘obscure Zenith chronographs’, which until then had not aroused the keen interest of connoisseurs.
The history of the appearance of this prototype has not yet been clarified in detail.
Some features raise questions, in particular the use of the manually wound caliber 146HP, produced by movement maker Martel Watch Co.
It is known that Zenith acquired this factory in the late 1950s. Martel, as an industrial division of Zenith, produced this caliber in the 1960s.
Then, after developing the self-winding 1969 launch El Primero, they concentrated entirely on its manufacture until 1975, when Zenith made the decision to stop the production of mechanical calibers.
However, there were movement remnants in stock at Zenith, including the venerable 146HP, which may have been used in some projects including the release of an all-black prototype chronograph wristwatch with a blackened case, black dial and dark grey ‘ghost’ hands.
There is no answer to the question why El Primero was not used in the manufacture of this prototype – though perhaps it is because its cost was higher than that of the 146HP.
