Strength and Zenith Defy El Primero 21, affordable machinery 1/100 second chronograph

www.greatwatcheshere.com.The zenith brings El Primero into the twenty-first century, with a new caliber of dual management.

Zenith in 1969 launched El Primero, became the first to launch automatic chronograph one of the watchmakers. El Primero is rugged, affordable, surviving in the quartz crisis and is now considered a milestone chronograph.

Over the past 50 years, El Primero as a chronograph did not change significantly until the 2017 Basel New World, by the newly developed El Primero 9004 movement to provide power, the zenith Defy El Primero 21 cover.

HUBLOT MP-05 LAFERRARI 905.NX.0001.RX WATCH replica.Large and quite thick - the shell size is 44mm diameter and 14.5mm high - Defy El Primero 21 has a technical appearance, especially in today's fashionable open version. Although reminiscent of watches from other brands, but the appearance of suitable for sports and function, making it a consistent packaging.

Will provide three variants of Defy El Primero 21, although the size is small. Both models have titanium alloy, and finally ceramic aluminum. Complete the alternating brush and polished surface, titanium shell than the full black ceramic aluminum more visually appealing.

In front, the choice is skull dial or silver, solid dial. Open dial is the most attractive, because the open dial reveals the following mechanism. Press the start button of the chronograph, and the middle second hand turns the middle second hand every second. A circle around the dial is made up of 100 infinitely small steps that the eye can not recognize. Stop the second hand that has passed the last one second.

The main feature of the movement is its "double chain" structure, with two balance wheel, gear train and clockwork - one for timing, the other for chronograph. This construction is not new, has been used by Montblanc and TAG Heuer, but technically still challenging.Graham Chronofighter Watches replica

This action is mainly exposed to the open version, many can be seen. But this is due to technical characteristics and structure rather than finishing, which is mute and simple, with plenty of sandblasting and direct grain parts.

 

 

 

On the open version of Defy El Primero 21, the timing wheel is visible at eight o'clock and its mainspring is at one o'clock. The speed is 36,000 times per hour, the traditional El Primero high frequency.

Through the back of the star rotor wound, the movement of the timing part of the conventional 50-hour power reserve. From the back of the second second, you can see a 1/100 second chronograph smaller balance wheel. Reduced size and short gossamer because it runs at 360,000 bph, which is ten times the normal balance wheel.RICHARD MILLE RM 011 FLYBACK CHRONOGRAPH BLACK WATCH replica

Since the balance oscillates at such a high frequency and consumes a large amount of energy, and because the space limits the size of the second winding, the second chronograph score has a 50 minute power reserve, which seems very brief, but in fact Is one hundred thousandth of a second.

Since the score of the second timer has its own power supply, it is wound through the crown alone; 25 turns to the whole wind. Both balance wheels are made of "carbon-based carbon nanotube composites". It is a composite of carbon nanotubes, which is lightweight and rugged, especially for oscillators, especially at high frequencies.

Defy El Primero 21 The internal El Primero 9004 movement is integrated, which means that the first machine 1/100 is not a separate module, the bolt is fixed on El Primero, which is a more convenient way to build this chronograph Table method.reviewbestselling.com

Zenith said that the internal development of the caliber and TAG Heuer Mikrograph internal function similar (even sub-dial located in the same place) is different.

Having said that, Jean-Claude Biver, chief executive of TAG Heuer and Zenith, said in an interview with Switzerland's NeueZürcherZeitung that the campaign was made up of a two-branded engineer Team and sister company HUBLOT.

Defy El Primero 21 will be the first half of the "Defy" watch to be re-launched in the second half of the 20th century called Zenith for the name of the sport watch. The new line may have a similar style, making Zenith a brand new road, but still very familiar.

Although the design has elements that can be recognized from other Zenith watches, angle boxes, flat borders and rectangular faders are reminiscent of Hublot. In fact, the crocodile skin and related folding clasp rubber band and Hublot watch the same.ZENITH DEFY EL PRIMERO 21 95.9000.9004/78.R582 WATCH replica
