The new El Primero Synopsis line 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. Thanks to its distinctive dial opening highlighted by a screw-fastened appliqué and revealing a glimpse of its silicon components, it has never been so easy to admire this movement in action.

Three models radiating strong emotional power

An avant-garde material featured in the El Primero Synopsis models, silicon represents a major breakthrough in the quest for the grail of mechanical watchmaking – namely 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. It is definitely a material with a promising future in pushing the boundaries of mechanical precision.

Listening to the swift and steady 36,000 vibrations-per-hour beat of the El Primero calibre is already a unique experience, but actually watching this fast-paced cadence in action takes things to a whole new level. That is exactly what is offered in the new El Primero Synopsis, a classic and elegant watch encapsulating the entire genetic heritage – and the vibrations – of the legendary models from the Manufacture Zenith. 
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 “engine” throbbing inside: El Primero Calibre 4613.

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.

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.

No less than 160 parts drive its mechanical automatic movement, El Primero Calibre 4613. Like all El Primero calibres, it beats at the exceptional frequency of 36,000 vibrations per hour, meaning 10 vibrations – a fast-paced clearly rhythm visible through the dial opening.
