prodUct information

materials

HigH-tecH ceramic

Innovative, durable and skin-friendly: introduced by Rado in 1986, high-tech ceramic has become our signature. In metallic or non-metallic colors, with a glossy, matt, satin-brushed or decorated finish, it is the most versatile of our materials.

HigH-tecH Hardmetal

Pure, simple and extremely tough: we pioneered the use of this material by introducing the world's first scratchproof watch, The Original, in 1962.

SappHire cryStal

Perpetual transparency: scratchproof high-tech sapphire crystal is used throughout our collection. The application of edge-to-edge crystal and metallization are distinguishing features.

HigH-tecH diamond

Incomparable and enduring brilliance: the Rado high-tech diamond surface offers hardness equal to that of natural diamonds. Our invention and use of this surface have earned us an entry in the Guinness Book of Records for the world's hardest watch.

HoW Hard iS Hard?

The extreme hardness of Rado high-tech materials guarantees durability and brilliance. The Vickers scale is used to indicate hardness: the higher a value, the greater the resistance to scratches. Rado materials commence at Vickers 1,200 – far higher than gold, steel or platinum. The topvalue of 10,000 is attributed only to natural diamonds and to the Rado high-tech diamond surface.

NOTE: Rado watches are hard but not indestructible. Although our high-tech materials are resistant to scratches, Rado watches must be treated with care. They should not be dropped, and sharp knocks should be avoided. If hit hard enough, the materials may break.

rado SUface finiSHeS

poliSHed

The incomparable hardness of Rado's high-tech materials gives the polished surface the deep luster and captivating brilliance uniquely associated with the brand.

Satin-brUSHed

The satin-brushed finish gives a semi-matt appearance that conveys a sense of understated sophistication while ensuring a subtle tactile pleasure.

matt

The matt finish adds depth to the surface, which reacts to the light in a way that reinforces the shape of the watch and brings out the richness of the material.

decorated

The surface is embellished with a motif in color. The decorated surface is the result of years of research, adding a new dimension to high-tech materials.

The extraordinary scratch and abrasion resistance of our high-tech materials is guaranteed, ensuring the durability of your Rado watch.

NOTE: Due to the hardness of the material and its matt or satin-brushed finish, so-called deposits may occur through contact with softer materials and may look like scratches. In most cases these deposits can be completely removed using a hard rubber eraser.

precioUS StoneS

The name “Jubilé” appears on the dial of all Rado diamond (or precious stone) watches. Details regarding the precious stones used on Jubilé watches may be found on the accompanying Precious Stone Certificate.

The quality of a diamond is defined by 4C's: Carat, Clarity, Color and Cut.

carat

The weight of a diamond is measured in carats. 1 carat is the equivalent of 0.2 grams.

Stones of various weight classes and sizes are used in Rado “Jubilé” models.

clarity

Rado diamonds are of the VVS class (Very very small: miniscule flaws that are scarcely recognizable even at tenfold magnification).

color

The color spectrum ranges from colorless — the most valuable — to yellow. Rado uses Top Wesselton (superior quality) diamonds.

cUt

The cut determines the fire, brilliance and the luster of the diamond. Nearly all Rado diamonds are classed as 8/8 or full cut (brilliant).

other precioUS StoneS

There is no uniform nomenclature for describing the purity and color of other precious stones. Rado uses only precious stones of the highest quality.

QUartz WatchHeS

Rado quartz watches are equipped with top-quality Swiss batteries. Under normal conditions, a battery should last at least 30 months. The battery must be changed when the seconds hand starts to move in 4-second intervals (or when, on a multifunction watch, the digital display begins to blink). Battery exhaustion in a watch without a seconds hand becomes apparent only when the hands stop moving altogether. Battery changes should only be performed by an authorized Rado dealer or Service Center to ensure that only original parts are used and that your watch is properly tested for water resistance. A worn-out battery should be replaced immediately in order to reduce the risk of leakage and consequent damage to the movement.

Rado Centrix Diamonds R30930712 - QUartz WatchHeS - 1

Collection and treatment of end of life quartz watches*: This symbol indicates that this product should not be disposed with household waste. It has to be returned to a local authorized collection system. By following this procedure you will contribute to the protection of the environment and human health. The recycling of the materials will help to conserve natural resources.

* Valid in the EU member states and in any countries with corresponding legislation.

aUtomatic WatchHeS

A fully wound Rado automatic watch has a running reserve of at least 36 hours. If the watch stops (e.g. if it has not been worn for some time or during periods of low activity), it should be wound manually. to wind an

automatic watch manually: place the crown in position 1. Turn the crown clockwise several times.

Water reSiStance

All Rado watches are water-resistant and have the word “Watersealed” engraved on the caseback. These watches can withstand water pressure up to a depth of 30 m (100 feet), which means that you can go swimming or take a shower while wearing your Rado. Water resistance is not a permanent condition. To ensure permanent water resistance, the watch should be checked once a year. To ensure conformance with the warranty regulations, these operations must be performed by an authorized Rado dealer or authorized Rado Service Center.

NOTE: Water resistance information in “meters” or “bar” refers to theoretical pressure and temperature test norms and does not indicate actual diving depths.

IMPORTANT: To ensure optimal water resistance, the following must be observed: after every operation involving the crown, return it to position 1 or screw it back in by pressing and turning it clockwise simultaneously. Avoid shocks to the crown. Do not use either the crown or chronograph pushers underwater.

maintenance

Please note that regular servicing will help to extend the life and maintain the value of your Rado watch. For perfect maintenance, please visit only your official Rado dealer or Service Center (a list of Rado Service

Centers can be found at the end of this manual or on the Internet).

Your bracelet will also benefit from being cleaned from time to time with lukewarm, slightly soapy water and the help of a toothbrush. This cleaning is especially recommended if the watch has been in contact with salt water or cosmetics.

Skin-friendlineSS

For Rado, luxury means not only aesthetic perfection and the choice of exquisite materials but also personal comfort. Apart from ensuring durability, our high-tech materials ensure that Rado watches are gentle to the skin and smooth on the wrist.

SWiSS precision

The name Rado guarantees a Swiss quality watch movement of the greatest precision. Every movement undergoes numerous controls before being installed in a Rado watch. The average deviation of a Rado quartz watch should not exceed 15 seconds per month. The average deviation of a Rado automatic watch should not exceed -5 to +20 seconds per day.

rado cChronometerS

All Rado chronometers are equipped with first-class Swiss chronometer movements known for their ultra-precise accuracy. Each movement is rigorously tested and certified by the Official Swiss Chronometer Testing Institute (Contrôle Officiel Suisse des

Chronomètres, COSC). This neutral and independent body individually tests each movement for 360 consecutive hours, during which it is placed in the five common wrist positions and exposed to three different temperatures. To earn the title of chronometer, the mechanical movement's average variation in rate must be between -4/+6 seconds per day, or a precision of 99.99% – the highest precision attainable by a mechanical movement. A special certificate accompanies all COSC-certified movements.

When pressed up against the case and screwed in, the crown ensures that the watch is water-resistant.

To set the time

Position 3

Pull the crown out to position 3. The small seconds hand will stop. Set the correct time by turning the crown forward or backward. Synchronize the seconds by pushing the crown back to position 1 to coincide with a given time signal.

Chronograph functions

Timing to within 1/8th of a second for up to 12 hours.

Make sure the chronograph hands are at zero (Pusher B).

Pusher A: Start – stop, start – stop etc.

Pusher B: Reset (after a stop).

Chronograph functions with split-seconds

The split-seconds function allows split times to be recorded while the chronograph is running.

  1. Start the chronograph by pressing pusher A.
  2. To record a split time, press pusher C. The split-seconds hand stops, indicating the split time, while the chronograph continues running.

NOTE: The split time should be read immediately, since the chronograph totalizers for hours, minutes and seconds continue to measure the elapsed time.

While the chronograph is running, do not leave the split-seconds hand stopped any longer than is necessary to read the split time, otherwise the functioning of the split-seconds mechanism may be affected.

  1. Press pusher C for the split-seconds hand to catch up with the chronograph seconds hand.
  2. To record a new split time, start from step 2 above.
  3. Press pusher A to stop the chronograph.
  4. Press pusher B to reset.

IMPORTANT: The split-seconds hand must have caught up with the chronograph seconds hand, as explained in step 3 above, before the chronograph is reset.
