The new El Primero Synopsis line comprising three references capitalises on a legendary movement while remaining true to several iconic Zenith signature touches. Accurately displaying the hours, minutes and small seconds at 9 o’clock, this watch beats at the rate of 36,000 vibrations per hour imparted by El Primero calibre 4613. Its distinctive dial opening highlighted by a screw-fastened appliqué reveals a glimpse of its silicon components.
Silicon represents a major breakthrough by eliminating the need for lubricants. The lever and escape wheel of the El Primero Synopsis models are made of silicon, harder than steel – which leads to reduced wear – and far lighter – which requires less force to achieve the same result – silicon also boasts a low friction coefficient and is both anti-magnetic and corrosion-resistant.
Since 1969, the El Primero watch has come to symbolise the creative genius of the Manufacture Zenith. This name, derived from Esperanto and thus conveying a spirit of universality with a humanistic touch, is embedded in the brand heritage and remains a powerful symbol of innovation.
First presented in 2003 and now a signature of the Manufacture, the unique Open concept is combined here with the use of silicon. A bird’s eye view into the heart of the movement provides a glimpse of the lever and the lever wheel made of silicon – a high-tech, anti-magnetic material ensuring excellent efficiency. Born in the protective shadow of the original El Primero calibre and its many evolutions, the new El Primero Synopsis is a fully integrated movement combines slimness, reliability and precision: the position of each plate, gear train and part is meticulously optimised.
No less than 160 parts drive its mechanical automatic movement, El Primero Calibre 4613 which beats at the exceptional frequency of 36,000 vibrations per hour. A dial opening provides a dizzying view of the regulating organ that ticks inside. Concern for details extends all the way to the screw-fastened appliqué framing the opening, and to the 12 rhodiumed facetted and superluminova-coated hour-markers ensuring a perfect display of the hours and minutes, swept over by two hands, while the seconds are ticked off by a blued trident hand whirling over the mechanism revealed at 9 o’clock.
A round case, a subtle dial design featuring perfect readability, together with pure lines throughout: such are the signature features of the new El Primero Synopsis by Zenith. However, what really sets it apart from its competitors is the opening revealing its exceptional mechanical heart.
The pink gold or steel 40 mm case frames an appealing silver-toned dial affording a view over the escapement of the exceptional El Primero Calibre 4613.
Guided by the same spirit and in keeping with the essential principles of watchmaking, a sapphire crystal ensures a truly beautiful view from both sides of the dial. These aesthetic virtues are backed by the reliability of a case that is water-resistant to 100 metres and fitted with a screw-lock crown, together with seamless case and wristband integration guaranteeing remarkably ergonomic comfort.
