How to use the tachymeter?

Start the chronograph at the beginning of a 1 km course. Stop it at the end. The second hand indicates the average speed on the tachymeter scale. For example, 45 seconds gives about 80 km/h.

How to use the telemeter?

Start the chronograph when you see a flash or flame, stop it when you hear the sound. The telemeter scale indicates the distance in km (up to 20 km).

Is the watch waterproof? Can I swim with it?

The water resistance is 30 meters (3 ATM). It is splash resistant, rainproof, and sweat resistant, but not suitable for swimming or diving.

How to clean my watch bracelet?

For metal bracelet: toothbrush with warm soapy water. For plastic/rubber: water only. For leather: soft dry cloth, inside with a cloth moistened with alcohol.

TACHYMETER

The tachymeter is the device which measures the speed of an automobile. Knowing in how many seconds the car covers a distance of 1km , the meter can measure the approximate average speed per hours during a journey (up to the maximum measurable range of tachymeter which is 60 seconds).

If the chronograph is started at the same time as measurement, and stopped after 1km , the average speed per hour can be determined according to the position of the second hand. If the car covers the distance of 1km in the 45 seconds, the average hourly speed during the journey will be about 80Km .

TELEMETER

The telemeter is a distance indicator which allows distance to be calculated on the basis of the speed of sound. It is useful, therefore, for aviation, navy, army and artillery purposes. It can also measure how far away a thunderstorm is.

The hand is started the second a flash, smoke or lightning is seen and stopped when the actual sound is heard. The distance, from 1 to 20 kilometres, between the observer and the explosion or storm is read from the telemetry scale.

• In order to prevent water coming into contact with the internal mechanism, never pull the crown out when the watch is wet.
• If any watches designed for sportswear or use in water come into contact with salt water or heavy sweating, they should be rinsed in fresh water and dried thoroughly.

* Always keep the crown in its normal position. * Full tighten crown screw lock.

• Contact with water may cause a deterioration in the quality of some leather straps.
• As internal parts of the watch can retain moisture, when the outside temperature is lower than the inside, the watch glass may mist-up.

This phenomenon is purely temporary and should not create any problems.

However, if it persists for any length of time, the watch should be checked by the shop where it was purchased or by the nearest Authorised Service Centre.

Temperature

Do not leave the watch exposed to direct sunlight or temperature extremes for long periods of time.

Long exposure, in fact, may adversely affect the operation of the watch and actually shorten battery life, causing it to gain or lose time and affect its other functions.

Impact

This watch can withstand normal everyday impacts and shocks and those normally imparted by non-contact sports. Serious damage, however, may result if the watch is dropped or subjected to severe shock.

Magnetic fields

This watch is antimagnetic up to 60 gauss, and is therefore not affected by magnetic fields produced by normal domestic appliances. If used near strong magnetic fields, its operation may be temporarily affected.

Static electricity

The integrated circuits present inside the watch are sensitive to static electricity. If the watch is exposed to intense electrical fields, the time display may temporarily lose some of its accuracy.

Chemicals and gases

Avoid wearing the watch in the presence of strong gases or chemical substances. Parts of the watch may discolour, dissolve or even break if brought into contact with benzol or petroleum based products such as solvents, thinners, detergent, adhesives etc.

Pay special attention to avoiding contact with chemicals.

The watch case and strap may discolour if they come into contact with mercury from a broken thermometer or other equipment.

Keeping the watch clean

Use an absorbent soft cloth to clean off any dirt or damp from the watch glass.

Wearing the watch when the strap or back of the case is dirty can cause skin irritation.

Cleaning the watch strap:

Metal bands: use a toothbrush and soapy warm water to wash the dirt off.
- Plastic or rubber straps: wash with water. Do not use solvents.
- Leather straps: gently rub the face of the strap using a soft dry cloth. Clean the opposite side with a cloth and alcohol.

Periodic inspection

In order to guarantee long trouble-free operation, it is advisable to have the watch checked by an Authorised Assistance Centre once every two years.

Keep batteries out of the reach of children

If a battery is accidentally swallowed, consult a doctor immediately.
