ZENITH – Defy EL PRIMERO 21 - Only Watch Edition

ZENITH – Defy EL PRIMERO 21 Skeleton Chronograph Titanium 44 - Only Watch Edition

On 11th November 2017, Only Watch will host the seventh edition of the charity auction in Geneva. Zenith is proud to be able to support this campaign by donating a unique edition of the breathtaking innovation of 2017, the Defy El Primero 21 Only Watch Edition.

It features a new 1/100th of a second chronograph and two completely independent movements, each driven by its own regulator. The 44 mm black DLC titanium case and signature yellow details on the dial make the Defy El Primero 21 a highly attractive, unique piece, further emphasized by the presentation box which has been exclusively designed for this watch. The lucky winner of the auction will also be able to enjoy a unique Zenith experience: a trip to the headquarters, to discover one of the most important Swiss watch Manufactures in the world. And Zenith has plans to ensure this visit will truly be an event to remember !

Created more than ten years ago, Only Watch has now become one of the largest charity events in the watchmaking industry's calendar, organized by the Monegasque Association against Muscular Dystrophy (AMM) and the Monaco Yacht Show. This annual auction sees all proceeds from the sale of one-of-a-kind timepieces donated to funding research into the extremely serious Duchenne form of muscular dystrophy, discovered by French neurologist Guillaume Duchenne in 1858, and to funding treatment, particularly for children.

This year, Swiss watch Manufacture Zenith is presenting a new special edition of the pioneering and revolutionary Defy El Primero 21. Launched at Baselword 2017, the Defy El Primero 21 is a masterpiece of modern engineering. Constructed using state-of-the-art methods and finished using the newest technologies and materials, the Defy El Primero 21 fulfils two objectives: a finish of the highest possible quality, and optimum performance and precision on the wrist.  First released in 1969, the world’s most accurate series-made chronograph entered a whole new era of mechanical timekeeping with the Defy El Primero 21. An impressive frequency of 360,000 beats per hour is testament to the groundbreaking ingenuity of Zenith, and enables precise measurement of time periods to a hundredth of a second. The jump from tenths to hundredths of a second is a quantum leap in terms of watchmaking performance and engineering.

For Zenith, precision is the absolute priority. To avoid any risk of the chronograph affecting the accuracy of the time display, the Defy El Primero 21 is equipped with a “double chain structure”. This means that the time display and chronograph each have their own completely independent mechanism with its own barrel and high frequency escapement. For the chronograph, this oscillates at a breathtaking 50 Hz (360,000 vph). As standard for the El Primero, the time display escapement oscillates at 5 Hz (36,000 vph). This means that the El Primero 21 has no need for the clutch mechanism traditionally found in chronographs.

Alongside the double-chain structure of the caliber, and the remarkable precision this ensures, the El Primero 21 boasts other technical highlights: a new, patented start/stop/reset mechanism composed of three heart pieces, and an exclusive starter mechanism which ensures reliable operation under all circumstances, and allows all chronograph displays to be simultaneously reset. In addition, the springs in both regulators are fully carbon; more specifically created from the ultra-light and incredibly stable carbon nanotube metal matrix composite. This world first ensures that the Defy El Primero is unaffected by magnetic fields and temperature changes as well as the influence of gravity.

The Defy El Primero 21 speaks to all of the senses, reflecting the aesthetic and acoustic signature of this new era for Zenith. The central chronograph hand rotates once around the dial each second, while the 50 Hertz escapement emits a pleasant "buzzing". The passing of time becomes endlessly fascinating to observe, whilst also enabling the 1/100th of a second display to be read reliably at a glance.

The Defy El Primero 21 Only Watch edition embodies the new generation of Zenith chronographs, combining pioneering technology with a timeless and dynamic exterior. As so often in the long history of the Zenith Manufacture, the Defy El Primero 21 is the first step towards the future of watchmaking. It also heralds many further pioneering innovations set to come from Zenith.

Only Watch Partnership

Now presenting its 7th Edition, Only Watch is a biennale auction of unique timepieces that has raised over 25 million Euros to date. Under the patronage of HSH Prince Albert II of Monaco and following the initiative of Luc Pettavino, President of the Association Monégasque contre les Myopathies, Only Watch is an international watchmaking charity event.

All of the funds collected from the sale of the watches are donated in their entirety to scientific and medical research. The exclusive watches will embark on a world tour starting in the charity’s hometown of Monaco, and then continuing to Asia, the Gulf, the United States and Europe, before the final auction in Geneva on November 11th 2017.
