Summary

LIMITED TWO-YEARS WARRANTY (USA)

LONGINES is delighted that you should have chosen a model from our prestigious collection. The little technical marvel you now own will serve you faithfully for many years. The most advanced techniques were used during its manufacture, and it underwent stringent controls before it was released for sale.

Your LONGINES® watch is warranted by Longines Watch Co. Francillon Ltd* FOR A PERIOD OF TWENTY-FOUR (24) MONTHS FROM THE DATE OF PURCHASE under the terms and conditions of this warranty.

The international LONGINES warranty covers material and manufacturing defects existing at the time of delivery of the purchased LONGINES watch (“defects”). The warranty only comes into force if the warranty certificate is dated, fully and correctly completed and stamped by an official LONGINES dealer (“valid warranty certificate”).

During the warranty period and by presenting the valid warranty certificate, you will have the right to have any defect repaired free of charge. In the event that repairs are improper to restore the normal conditions of use of your LONGINES watch, Longines Watch Co. Francillon Ltd guarantees its replacement by a LONGINES watch of identical or similar characteristics. The warranty for the replacement watch ends twenty-four (24) months after the date of purchase of the replaced watch.

This manufacturer’s warranty does not cover:

the life of the battery;

normal wear and tear and aging (e.g. scratched crystal; alteration of the colour and/or material of non metallic straps and chains, such as leather, textile, rubber; peeling of the plating);

any damage on any part of the watch resulting from abnormal/abusive use, lack of care, negligence, accidents (knocks, dents, crushing, broken crystal, etc.), incorrect use of the watch and non-observance of the use directions provided by Longines Watch Co. Francillon Ltd;

the LONGINES watch handled by non-authorized persons (e.g. for battery replacement, services or repairs) or which has been altered in its original condition beyond Longines Watch Co. Francillon Ltd’s control.

ALL APPLICABLE IMPLIED WARRANTIES, INCLUDING THE IMPLIED WARRANTY OF MERCHANTABILITY AND OF FITNESS FOR A PARTICULAR PURPOSE GIVEN TO YOU BY LAW ARE HEREBY LIMITED IN DURATION TO THE DURATION OF THIS WARRANTY. UNDER NO CIRCUMSTANCES WILL LONGINES WATCH CO. FRANCILLON LTD BE LIABLE FOR ANY INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND.

Some states do not allow limitations on how long implied warranties last, or exclusions or limitations of incidental or consequential damages, so exclusions or limitations mentioned may not apply to you. This warranty gives you specific legal rights and you may also have other rights which may vary from state to state.

RECOMMENDATIONS

Like any micromechanical precision instrument, your LONGINES watch should be checked at least every two years.

If you have a self-winding watch, it has a power-reserve of around two days. If necessary it can be wound manually.

If you have a quartz watch the electrical power is supplied by a battery. After 12 to 18 months of use (with the exception of watches with lithium batteries) the voltage in the battery may drop suddenly and cause your watch to stop. Some models have a battery end-of-life function. The seconds hand will start to jump every 4 seconds. If this happens we recommend that you replace the battery immediately, because once the battery runs down totally it may damage your watch.

tion 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.

Replacing the battery

We recommend that you contact an approved LONGINES service centre or authorised LONGINES retailer, as they are equipped with the tools and apparatus required to carry out the work and the necessary checks in a professional manner. A worn-out battery should be replaced immediately in order to reduce the risk of leakage and consequent damage to the movement.

54	International guarantee / Recommendations

What can I do to ensure that my LONGINES watch functions perfectly for many years?

Magnetic fields: avoid putting your watch on a loudspeaker or on a refrigerator because these machines create magnetic fields that may damage it.

Salt-water: always rinse your watch in fresh water after swimming in the sea.

Shocks: avoid subjecting your watch to any shocks, including sudden changes in temperature.

Screw-in crown: always make sure you have screwed the crown in fully to avoid any humidity getting into the mechanism.

Push-in crown: always push the crown back into the neutral position to avoid any humidity getting into the mechanism.

Cleaning: use a tooth-brush and soapy water to clean metal bracelets and water-resistant cases and a soft cloth to dry off afterwards.

Chemical products: avoid all direct contact with solvents, detergents, perfume, cosmetics, etc. which may damage the bracelet or strap, the case or the seals.

Temperatures: avoid exposing your watch to extreme temperatures (over 60°C or 140°F and under 0°C or 32°F) and to sudden fluctuations in temperature.

Water-resistance: we cannot guarantee that your watch will be permanently water-resistant. The seal may be affected by wear or by an accidental shock to the crown. As recommended in our service instructions, you should have the water-resistant seals of your watch tested once a year by an approved LONGINES agent.

SPECIAL RECOMMENDATIONSRecommandations

Chronograph push-pieces: do not adjust the push-pieces under water as this may allow humidity to get into the mechanism.

Occasional winding: if your watch has not been worn for 44 hours or more, wind it manually with the crown in position 1.

How often should my watch be serviced?

Like any other precision instrument a watch should be serviced regularly to ensure that it runs perfectly. We cannot say how often you should have your watch serviced as this depends on the model, the climate where you live and how you look after the watch yourself. As a rule, a watch should be serviced every 4 or 5 years, depending on the conditions in which it is worn.

Where should I go to get my watch serviced or for a new battery?

We recommend that you go to an approved LONGINES agent or retailer. They are the only people who have the necessary tools and apparatus to work on your watch and to carry out the necessary checks to a professional level. Moreover, only specialists can guarantee that their work meets the stringent quality standards set by LONGINES.

RUBBER STRAP

• Excellent resistance to water and wear	• Incomparable suppleness and softness to the touch
• Superb mechanical properties	• Hi-tech product
• Very good resistance to aggressive and extreme	• Top-range quality
environments	• Hand-finished

We recommend that, if necessary, you have the length of your strap adjusted by a Longines agent.

Detach the two covers over the clasp by pressing on the bars.

Measure the circumference of your wrist by wrapping the strap round it. Half the number of holes that overlap indicates the length that suits your wrist.

Example: half resulting in an even number: 8 overlapping holes, half of 8 is 4, remove 2 holes on each section.

Half resulting in a odd number: 14 overlapping holes, half of 14 is 7, remove 4 holes on the section of the strap at 12 o’clock and 3 holes on the section at 6 o’clock.

Cut along the corresponding graduations.

Reinsert the bars in the two sections of the strap.

Attach the sections to the clasp so that the graduations are on the inside, i.e. against your skin, insert the bars in the holes closest to the centre of the clasp.

Try your watch on.

For the final adjustment, move the bar to one of the holes in the clasp.

If the strap is too long, you can remove another hole.

We recommend that you wash your rubber strap regularly with soap and water, especially on the inside.

FOLDING CLASP

Adjusting the clasp

Release the adjusting mechanism by removing the pin from the hole in the long section of the strap.

Slide the mechanism along this long section and then fix it by reinserting the pin in the desired hole.

Opening the clasp

To open the clasp press in the push-pieces on either side simultaneously.

Open the clasp to enlarge the bracelet and remove the watch from your wrist.

Closing the clasp

Put the bracelet on your wrist and slide the long section through the small fixed buckle.

Close the folding clasp until it clicks into place. If necessary, slide the long section through the small mobile buckle.

WATER-RESISTANCE / CROWN AND SCREW-IN PUSH-PIECES

Precautions regarding water-resistance

If your watch is water-resistant it is essential that the seals be checked each year before the bathing season because, without your realising it, they might have been damaged as the result of a shock.

If the case has to be opened for any reason the seals for the glass and the case-back as well as the crown (and/or push-pieces) must be checked and, if necessary, replaced.

Screw-in crown and push-pieces

Certain Longines models have a screw-in crown which has to be unscrewed before each adjustment by turning it anti-clockwise (fig. ).

After use, return the crown to position 2, then push in and screw in firmly in position 1 to ensure that the seal with the case is water-resistant (fig. ).

THE SAME APPLIES FOR THE SCREW-IN PUSH-PIECES

IMPORTANT! You should always push the crown (and/or the push-pieces) right in and screw in firmly to ensure a water-resistant seal with the case. The crown (and/or push-pieces) should never be adjusted if the watch is in a humid atmosphere.

Power-reserve indicator

Pull the crown right out to position 3. The seconds hand will now stop. Adjust the time by turning the crown in either direction. Synchronise your watch with a time signal (telephone, radio, TV) and then push the crown back in to position 1. The seconds hand will jump again exactly one second later (logical function of adjusting the time), which means that your watch will now be perfectly synchronised with the time signal.

Quick date adjustment

Pull the crown out to the intermediate position 2. Adjust the date by turning the crown in either direction. Push the crown back in to position 1.

Certain watches have a power-reserve indicator (calibres L602, L693, L697).

If the watch is worn rarely or not at all, the hand will gradually shift anti-clockwise. When it indicates that the power-reserve is below 1/4, the watch should either be wound or worn to avoid it stopping.

When the watch is wound the power-reserve indicator will shift clockwise.
