ZENITH SINCE 1865 SWISS WATCH MANUFACTURE

Having invested in a ZENITH chronograph, you are now wearing a Manufacture watch.

ZENITH is part of a select circle of authentic Swiss watch manufactures that develop and produce their own movements. Since 1865, we have been manufacturing our watches in the same place, at our Manufacture at 34 rue des Billodes, in the village of Le Locle situated in the mountainous valleys of the Canton of Neuchâtel. There are few brands in the world that can pride themselves on having an approach as rigorous as ours. From the very moment you invest in a Zenith watch, you can be absolutely certain that you are in possession of a watch that has been produced from start to finish at the Le Locle Manufacture.

Having won more than 2333 chronometric observatory prizes, ZENITH is one of the Swiss brands that has been most highly rewarded in terms of accuracy. You can further share our passion for this fine craft by visiting our website www.zenith-watches.com. As an owner of a ZENITH watch you are invited to sign up. By doing so, you will receive an additional year's warranty. Your chronograph features a mechanical movement that is the product of more than 300 years of traditional watchmaking. We ask that you take care of it and are careful when making any adjustments. In the following pages you will find information on how to use your watch and its functions. The functions available depend on the model.

1 → EL PRIMERO 21 MOVEMENT

In front of you is the El Primero 21 movement. It is the only mechanical 1/100th of a second chronograph movement.

The El Primero 21 movement is a masterpiece of modern engineering. Constructed using state-of-the-art methods and finished using the newest technologies and materials, this movement fulfils two objectives: a finish of the highest possible quality, and optimum performance and accuracy on the wrist. First released in 1969, the world's most accurate series-made chronograph entered a new era of mechanical timekeeping with the El Primero 21 movement.

An impressive frequency of 360,000 vibrations 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, accuracy is the absolute priority. To avoid any risk of the chronograph affecting the accuracy of the time display, the El Primero 21 movement 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 calibre oscillates at 5 Hz (36,000 VpH).

2 → WINDING THE WATCH

Your watch is fitted with an automatic mechanical movement. The movement is wound via the crown or the effect of the oscillating weight. Winding via the oscillating weight takes place when the watch is on your wrist.

When your watch has stopped

The crown must be in the position 0, meaning it should be pressed against the case.

With the watch in your hand, turn the crown counter-clockwise. Turn the crown 72 times to fully wind the watch. The barrel that contains the mainspring has now been wound. In order for the automatic winding to work properly, the watch must be worn for at least 12 hours per day, for several days. Not wearing the watch enough causes it to stop.

If you do not wear your watch during the night, turn the crown a few times the following morning before you put it on.

Having been wound, the power reserve of your watch is around 50 hours, but this does not appear on the dial. Only the chronograph power reserve appears on the dial of your watch.

CHRONOMETER CERTIFICATION

The El Primero 9004 movement has been certified as a chronometer by TIMELAB in Geneva. It has been tested and successfully meets the requirements set by the ISO3159 standard.

A chronometer is a device that measures time to the highest accuracy, and can be adjusted to different positions and under a range of temperatures.

3 → WINDING THE CHRONOGRAPH

Alongside the double-chain structure of the calibre, and the remarkable accuracy this ensures, the El Primero 21 movement boasts two other technical innovations: 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 the chronograph second, tenths and hundredths displays to be simultaneously reset.

Procedure

The crown must be in the 0 position, meaning that it should be pressed against the case.

With the watch in your hand, turn the crown clockwise until the hand of the chronograph power reserve is fully wound (around 25 turns). The barrel that contains the mainspring has now been wound.

Fully wound, the chronograph power reserve is around 50 minutes. This is displayed by the hand located under the Zenith logo.

4 → SETTING THE TIME

Position 0: winding position

In this position you can manually wind your chronograph movement and watch by turning the crown. Pull the crown out a notch to change to position [1].

Position 1: correcting the time

To correct the time, turn the crown in the required direction.

Do not forget to return the crown to position (0).

5 → TIMEKEEPING FUNCTION

[A] [B] [C]

Switching it on/off: a single press of the push-button (A) switches the timekeeping function on, pressing it again will switch it off. Reviving the timekeeping function: pressing the push-button (A) again will revive the timekeeping function.

Resetting the chronograph: Once the chronograph has stopped, one firm press on the push-button (C) will send the hand of the chronograph back and the totalisers back to zero.

Warning: Before switching the timekeeping function on, the hands of the chronograph must be reset. If necessary, reset using the push-button (C).
