Zenith The Big Blue El Primero with Chatelain Bracelet
Some call it the Zenith TV others call it the Big Blue. Truth of the matter is this chronograph is exceptionally sought after. Its resemblance to a 1970’s television set coupled with its revolutionary mineral crystal and an El Primero movement merges to create a very special watch. Interesting details about these chronographs are its steel bracelets. Early versions of the watch came fitted with thick bracelets manufactured by a company called Chatelain, which coincidentally went out of business soon after. This event prompted Zenith to use a less appealing bracelet variant, the NSA bracelets. Big Blue’s fitted with Chatelain’s are rarer, therefore substantially more collectible.
