The chronograph can be read using the 1/10th of a second scale at the dial's periphery, allowing for the measurement and reading of elapsed time in precise fractions of a second.

Visible through the sapphire display back, the new architecture features a sleeker and more open design, revealing a blue column wheel and open rotor marked with the five-pointed star Zenith. Its autonomy has also been rendered more efficient, with an extended power reserve of 60 hours. With its high frequency of 5 Hz (36’000 VpH), the movement is able to precisely offer a true 1/10th of second indication.

Inside, the Chronomaster Original is equipped with the latest version of the El Primero calibre, dubbed the El Primero 3600. The steel bracelet has also been reimagined, foregoing the open “ladder” design of the 1960s for solid links that are sumptuously chamfered and decorated in the same fashion as the case.

Thankfully, it retains the A386 visual footprint, from the 38mm round bezel-less steel case with a raised and domed crystal, the pump-style chronograph pushers, the faceted lugs, the interplay of radial brushed and polished surfaces, and of course the emblematic dial with its tri-colour chronograph registers in shades of grey and blue, the trapezoid date window at 04:30 and the red chronograph second hand.

The legendary A386 finally names its successorįew watches have been as influential and truly iconic as the Zenith A386, which made its debut in 1969 as one of the first steel watches to be equipped with the revolutionary El Primero calibre – the world’s first automatic high-frequency integrated chronograph movement. New for 2021, the Chronomaster Original is neither tribute nor re-issue – it is an entirely new reference which masterfully retains the singular and enduringly relevant design of the A386 while packing the performance of the 21st century version of the El Primero boasting 1/10th of a second precision and time measurement.
