Defy El Primero 21 Watch El Primero Star Speed ​​legend Enters The One Hundred Seconds Era

Swiss watchmaker Zenith has gone through a century and a half, and it will resolutely enter the 21st century with its new one-second chronograph movement. The 21st century Defy El Primero watch inherits the roots of legend, while showing outstanding performance: COSC (Swiss official observatory inspection agency) certified self-mainframe-driven central hand to achieve a hundredth of a second display, one rotation per second — Quite dynamic and distinctive. Its double-chain structure is based on two regulators and is made of a carbon-based carbon nanotube composite. This is a new patented material that is insensitive to magnetic fields and temperature gradients, well above existing standards. The Defy El Primero 21 comes with a domineering 44 mm titanium case for extreme precision. In 1969, the world’s most accurate production chronograph entered a new era.
   Zenith has become a recognized king of high-frequency chronographs with its traditional El Primero star-speed movement, and today it once again reaches the ultra-high precision watchmaking world with the Defy El Primero 21 watch. From tenths to one hundredth of a second, a huge leap in performance and design has been achieved.

Soaring from 10 to 100
   1969: With El Primero (meaning ‘first’ in Esperanto), Zenith adds extraordinary color to the legendary chronograph history: integrated automatic column wheel mechanism with 36,000 vibrations per hour (5 Hertz) Vibration at high frequencies, making it accurate to a tenth of a second of a certified astronomical watch. To date, it is still the world’s most accurate production chronograph. The same gene, but a new record in the new century-Zenith has further improved the performance of the movement. The Defy El Primero 21 displays a hundredth of a second with a central pointer and a vibration frequency of 50 Hz, ten times faster and more accurate than its famous predecessor. Become the first achievement in the new products gathered by the stars.
   Precision, speed, and reliability: Today’s Defy El Primero 21 and the 1969 El Primero star speed are the same. The brand has a record 2,333 time-testing awards. The main difference is that the new generation of products has been developed with the aim of industrialization from the beginning. 32 mm in diameter, compared to 30 mm in the previous generation; 7.9 mm thick, compared to 6.50 mm; today includes 203 components, compared to 278 components in 1969. Mechanical functions are more complex, but the number of components is smaller: also in the automotive and aerospace industries, the Defy El Primero 21 is derived from modern engineering technology and uses statistical dimensions to match functional dimensions to machine functions, all designed to ensure simplified assembly and adjustment To achieve the best level of performance and certification.
   Therefore, the new watch is equipped with the new El Primero star speed movement, which has higher performance and is equipped with new adjustment mechanism and patented timing control mechanism. This modern movement is COSC-certified and measures one hundredth of a second, demonstrating its ambitious goal: to establish itself as the ‘most accurate timepiece’ brand on the market today. The watch is enriched with modern technology and traditional craftsmanship, combining Zenith’s rich history with cutting-edge clock innovation.

Double reconstruction frame
   The central chronograph hand rotates a full circle around the dial in one second, highlighting the aesthetic, visual and auditory characteristics of the new Defy El Primero 21. Reading in hundredths of a second is simple, fast, and direct, giving you a sense of the moment.
   The frequency reaches a staggering 360,000 vibrations / hour, ensuring its accuracy of one hundredth of a second, and energy consumption is ten times higher than before.
   There is another unique feature whose purpose is to avoid the chronograph function disturbing the smooth operation of the watch. This feature is: Defy El Primero 21 is equipped with two independent ‘gearboxes’: one for displaying time and the other for timing . Each ‘gearbox’ is equipped with its own transmission and escapement, so there is no coupling clutch.
   To pay tribute to its historical roots, the balance of the watch oscillates at a high frequency of 5 Hz-the famous and iconic 36,000 vibrations / hour that the El Primero chronograph movement has been famous for since 1969. This self-winding movement is as accurate as ever, certified by COSC, providing a 50-hour power reserve, and with a 50-minute battery life that matches the accuracy of the hundredth of a second.

Hairspring uses carbon-based carbon nanotube composite material (new patented material)
   In 1865, the founder of the young and visionary Zenith, Georges Favre-Jacot, brought together the different types of watchmaking that were usually scattered under one roof, creating the industry The first watch factory. Today, this spirit of independence and comprehensive skills is fully reflected in the new El Primero 21 self-moving core with its own patented hairspring. Gravity, temperature, and magnetic fields, all kinds of hostile characteristics that are not incompatible with precision, are completely neutralized.
   The new hairspring developed by LVMH Group engineers is derived from a patented technology that is also the world’s first. This hairspring is made of graphene-based composites with extraordinary physical and mechanical properties, so it is insensitive to temperature and magnetic field influences, far exceeding the known 15,000 Gaussian standard, guaranteeing availability under all conditions of use Unparalleled accuracy.
   In addition to the integrated structure, double-chain construction and excellent timing performance of the new hairspring, the El Primero 21 movement is also equipped with a patented timing reset control mechanism, consisting of three core components and a unique starter mechanism, ensuring simultaneous reset seconds And tenths and hundredths of a second.
   This new generation of dual barrel El Primero star-speed movement drives the central hours and minutes function, a small seconds hand at 9 o’clock, a central chronograph hand with a hundredth of a second rotating around a scale on the circumference, 30 at 3 o’clock Minute chronograph, seconds and tenths of a second at 6 o’clock, and chronograph power reserve indicator at 12 o’clock. The two-position crown (for winding and time setting) can be wound manually in two directions: for the chronograph function, clockwise, for the watch, counterclockwise. Rotating the crown 25 turns is enough to power the timepiece barrel. One-way automatic winding with star-notched automatic rotor / star-shaped skeleton automatic rotor control function.

Iconic ‘hundredth of a second’ display
   Defy El Primero 21 is based on modern mechanical technology and has been given unprecedented visual, auditory and dynamic characteristics. It is a model of Zenith’s new generation of chronographs.
   It proudly demonstrates the heritage of a watchmaker with a long and professional timekeeping expertise, while incorporating the most cutting-edge breakthrough technology. The essence of this brand can be seen in the stunning design of the watch-the case diameter is 44 mm, made of grade 5 titanium-inspired by the original El Primero model. The case is equipped with a grooved crown and chronograph buttons, and short lugs, alternately matte and satin finish; its rubber watch with leather inlays and double folding clasp.
   The hundredth of a second display is designed as follows: the inner bezel is designed with 0 to 100 graduations, and the hundredth of a second chronograph hand sweeps across the inner bezel at a speed of one full revolution per second-quite intuitive and visually striking force.
   The hollow dial reflects the elegant contemporary decoration style, which is also the representative aesthetics of Zenith’s new series. Star-shaped sweep seconds hand, large luminous rod-shaped hands and faceted hour markers: all the important identifying characteristics of El Primero are integrated, and the chronograph dial uses the two from the 1969 legendary chronograph Colors — blue and dark gray.
   Defy El Primero 21 — a benchmark for authentic Swiss watchmaking, hope for future creativity.
