Providing an unobstructed view of its legendary mechanism, the famous automatic Zenith Chronomaster El Primero “Full Open” wristwatch is aptly named, since it can now reveal the heart of its performance and precision thanks to a dial that is now entirely open – and “openworked.”
To ensure a better understanding of the fundamentals governing its flagship Chronomaster collection, Zenith offers its legendary El Primero chronograph in three different versions: with an entirely solid (closed) dial, a half-open (Open) dial, and now an entirely open (Full Open) dial. The latter is the most modern and contemporary interpretation, representing a major re-launch for the collection.
This complete opening enables users to grasp and visually appreciate the high frequency of the movement, the signature of the legendary El Primero integrated automatic column-wheel chronograph calibre with its 326 components (including 31 jewels), beating at the swift pace of 5 Hz (36,000 VpH) and thus capable of measuring and displaying the time with tenth-of-a-second precision. These attributes are inherited from its illustrious predecessor, the world’s most accurate series-produced chronograph developed by Zenith in 1969.
While the mechanism is now entirely revealed, there are nonetheless a few subtle nods to the historical version of the El Primero 1969: the date window of the 38mm version has been placed between 4 and 5 o’clock just like the original; and the famous blue colour is perfectly identical to the historical version. Combined with the two other colours, anthracite and rhodium, the three galvanic tones make a perfect match serving to magnify the movement.
