Top Grade Zenith – Defy El Primero 21 Replica Expensive

Defy El Primero 21

Since its creation more than 150 years ago, Zenith watches beaverbrooks Replica has constantly played a pioneering role in the development and production of precise, reliable and complex timepieces. By incorporating the entire range of watchmaking professions under its roof, the Manufacture in Le Locle has access to the full range of skills as well as the independence required to create unusual mechanisms, constantly pushing the limits of time measurement. Vividly embodying this amazing mastery, the El Primero caliber launched in 1969 is acknowledged by collectors and devotees of fine mechanisms as the most iconic chronograph in the history of the Swiss watch industry.

Nonetheless, chronometric performance remains a never-ending quest for the brand with the guiding star. Under the impetus of Jean-Claude Biver, CEO of Zenith and President of the LVMH group’s Watches Division, Zenith is presenting this year at Baselworld the Defy El Primero 21, with a new chronograph movement capable of measuring short times to the nearest 1/100th of a second. Combining 21st century engineering technologies with the purest horological traditions, this caliber houses several striking innovations, starting with a brand-new type of balance spring composed of carbon nanotubes, a composite material that is impervious to magnetism and temperature, made using a patented Zenith production process. The El Primero 21 movement is also distinguished by its double-chain structure. The first one, entirely dedicated to the watch functions, is inspired by the historical caliber and oscillates at a frequency of 36,000 vibrations per hour. The second, which controls the chronograph, beats at a rate of 360,000 vibrations per hour – a 50 Hertz frequency that makes the chronograph ten times faster and more accurate than its 1969 predecessor. Alongside its integrated construction, its double-chain architecture and the remarkable chronometric performance of its new balance-springs, the El Primero 21 movement features a patented chronograph-reset control mechanism composed of three heart pieces and an exclusive starter mechanism, ensuring simultaneous resetting of the seconds as well as tenths and hundredths of a second. With the Defy El Primero 21, the only series-made chronograph delivering 1/100th of a second precision currently on the market, Zenith makes a brilliant entry into a new era firmly geared towards modernity.

The second, more impressive feature, however, is its unusually high frequency. It beats 10 times per second, or 36,000 BPH, 25% faster than an ordinary modern watch, but an astonishing 100% faster than many watches at the time it was released. It quickly developed a strong reputation for accuracy and precision. In fact, the El Primero in this watch is, if the name didn’t give it away, a certified chronometer, and it thus carries with it a greater guarantee of accuracy than even most other El Primeros. Because it’s one of very few chronographs that beats 10 times per second, it can also measure events in 0.1 second increments, supposing that your reaction time is up to the challenge.One reason that our Timeless Chronomaster Heritage has been able to avoid the obesity that’s befallen many of its counterparts is because the El Primero is what is commonly called an integrated chronograph. In general, there are two kinds of chronographs, integrated ones, like you see here, and modular chronographs, which are also very common. Modular chronographs take an ordinary, non-chronograph movement and add a chronograph module to it. This makes it relatively easy for a company to produce chronographs because it doesn’t require the creation of an all-new movement from scratch, but it generally results in thicker than necessary movements.
