Frequently Asked Questions

You can be sure you are buying a genuine Longines product if you follow these steps:

 
  • Only buy a LONGINES product from authorized Longines retailers
 
  • Be sure to ask for the credit-card size guarantee, duly completed with the serial number, the watch reference and the retailer's full name and address.

Longines guarantees repairs and the delivery of spare parts for its watches for at least 15 years from the date production is discontinued. Beyond this time, Longines will do its utmost to ensure vintage watches can be maintained and therefore recommend returning the timepiece in question to our factory in Switzerland.

Like any other precision instrument working 24 / 7, 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 6 to 8 years, depending on the conditions under which it is worn.


    • 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 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 in to the neutral position to avoid any humidity getting into the mechanism.

    • Cleaning: use a toothbrush 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.

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

    On this site you will find all Longines products via the WATCH SELECTOR function. Please note that certain watch models found on the website are not available in all countries. For additional information, don't hesitate to contact an official Longines agent.

    All modern Longines watches are crafted according to the norms of the Swiss watchmaking industry (NIHS) and are water-resistant to 30, 50, 100 or 300 metres, depending on the model of watch. At the time of purchase, the water-resistance of your watch is symbolized by one of the following icons:

     

     

    Please note that the water-resistance of a watch is not a permanent characteristic. It may notably be affected by the ageing of gaskets or by an accidental shock to the crown.

     

    The water-resistance should be tested regularly, and at least once a year, by a Longines authorized Service Center.

     

    Furthermore, we insist on the fact that, without any supplementary indication of pressure, our watches should not be used for scuba-diving.

    If your Longines watch needs to be repaired, adjusted or serviced, we recommend that you bring or send it (well-padded and by registered delivery in the latter case) to your nearest Longines authorized service centre. You will find its address in your guarantee booklet or on our website in the Customer Service section.

    Longines guarantees the availability of its spare parts during a minimum of 15 years from the date of the production stop of the watch model concerned.

    If this period has elapsed and the spare parts are no longer available, we kindly suggest that you send your watch via a Longines authorized service center to the Longines head office in Switzerland for a repair estimation.

    In the large majority of cases, we are able to find a solution for repairing your watch properly even many years after the minimal duration of 15 years has elapsed.

    Please contact our customer service center to arrange to have your watch serviced. You may call them at 1-800-897-9477.

    Battery life varies usually from up 12 to 18 months depending on the type of movement that operates the watch. For the Conquest V.H.P. line, battery life may be up to 5 years.

    The service is subject to the individual condition of each watch. To find out the service costs for your Longines watch, please contact the authorized Longines Service Center in your area.

    If you need spare parts for your Longines watch, we recommend that you contact the nearest authorized Longines service center.

    Like any high-precision instrument working 24/7, you should service your watch regularly to ensure that it runs perfectly. How often you should service your watch depends on the model, the climate where you line and how you look after the watch yourself. Depending on the conditions under which you have worn your watch, you should send your watch in for service every 4 to 5 years.

    Please contact our Customer Service Center to arrange to have your battery replaced at 1-800-897-9477.

    • Automatic watches: the automatic winding device of an automatic watch keeps the watch wound while you are wearing the watch. Off the wrist, it will keep functioning for a number of hours depending on the usage. The automatic winding mechanism requires up to 10 hours on the wrist (depending on the model and on the activities of the wearer) to wind the watch completely. In order to guarantee the rate precision and a sufficient power reserve from the very first moment you wear the watch, we recommend that you wind the watch manually by turning the winding crown about 20 times clockwise. Repeat the same operation if your watch has stopped completely.

      If your watch has stopped and you simply wear it without winding it, it may not accumulate full power reserve and may stop again after you remove it from your wrist.

    • Quartz watches: a battery powers the quartz movement within the watch. Standard batteries will last approximately 12 to 18 months, before a sudden loss of energy causes the watch to stop. Some watches are fitted with a battery end-of-life (E.O.L.) indicator. When the battery is about to run down, the seconds hand starts to jump every four seconds. When the E.O.L indicator is active, replace the battery immediately. A powerless battery inside a watch might leak and damage its movement.

    • Warranty: always have your watch checked, serviced and repaired by an authorized Longines agent to maintain your warranty and ensure that your watch service meets Longines's quality standards.

    • Magnetic fields: all Longines mechanical watches can resist usual magnetic fields found in regular environments.
      However, it is possible for a watch to become magnetized if it is in direct contact with a very strong magnetic field (large speakers, large electromotors, fridges, computers, mobile phone holders with magnetic clips, etc.). If you suspect that your watch has become magnetized, please contact a Longines Service Center for assistance.

    • Crown: We recommend keeping the crown pushed in at all times when not adjusting the time or date. If you have a diving watch, we recommend you screw the crown back in carefully, after adjusting the time, to avoid water entering the movement. If you have a Conquest V.H.P. and want to put the watch into Energy Saving Mode, pull the crown out to position one and store in a safe place.

    • Seawater: We recommend that you rinse your watch with fresh water after every dip in the sea.

    We create all of our watches according to the norms of the Swiss watchmaking industry (NIHS). Modern Longines watches are water-resistant to 30, 50, 100 or 300 meters, depending on the model of watch.

    However, a hard knock might cause the watch to lose its water-resistance without you realizing it. Therefore, if you plan to use your watch underwater, it is essential to have the water-resistance checked at least every 12 months and the seals replaced by an authorized repair center every time you replace the battery.

    Yes, we can supply the following information depending on what we are able to find in our archival records:

    • Type of watch and material
    • Type of movement
    • Invoice date
    • Name of the invoiced dealer
    • Destination country
    • Model reference number
    • Model name or name of collection it belongs to
    • Suggested retail price at the time of model launch

    Depending on the watch, only some of this information may be available; we only give out information when we have corroborating sources.

    In order for us to carry out research on your watch, we require the following information:

    • A description of the watch (type of watch, material, etc.)
    • Watch serial number in addition to any numbers and markings engraved on the watch, specifying where the engraving can be found
    • A few good quality photographs (face, reverse, if possible the inside of the case back and the movement) that will easily allow us to see all of the engravings on the watch.

    The serial number, or consecutive number, is essential in finding the information relating to your watch. According to the era, this number (consisting of numeric characters only) can be engraved in various places:

     
    • On the outside of the case back (this is common for more recent wristwatches)
     
    • Inside the case back
     
    • Inside the lid for pocket watches
     
    • On the watch movement
     

    As such, you may need to have the watch opened by a jeweller.

     

     

     

     

    We do not supply estimated values for previously owned watches. This is due to market fluctuations in the antiques sector in which we have no activity. We suggest that you contact an antiques dealer or an auction house specialised in timepieces.

    A watch movement acts as the powerhouse to make the watch and its functions work. The internal mechanism can be an automatic movement, a quartz movement, or a manual movement. The movement inside the watch moves the hands and powers any complications the watch has.

    A quartz movement uses an electronic oscillator regulated by a quartz crystal to keep time. The movement causes the second hand to move in individual ticks, and is powered by a battery.

    Often referred to as self-winding, an automatic watch is a mechanical watch in which the mainspring is wound automatically as a result of natural motion of the wearer's arm to provide energy to run the watch. Automatic watches do not require batteries.

    A chronograph is an instrument for recording time.

    A chronometer is a specific type of mechanical timepiece that the COSC certifies to meet certain precision standards.

    A rotating bezel allows for an easier read of elapsed time while under water. Most diving watches have a unidirectional bezel or bidirectional bezel, which can rotate in a counter-clockwise direction or in both directions, respectively.

    The End Of Life indicator is a signal of the watch's battery running low. When the battery is running out of power, the seconds hand starts to jump every four seconds. When the E.O.L indicator is active, we recommend replacing the watch's battery promptly.

    PVD is short of “Physical Vapour Deposition” and consists in covering the entire surface of your watch, and often its bracelet, with a thin layer of titanium nitride, an extremely dense and exceptionally hard metal compound. Effected in a vacuum, this coating provides your watch with efficient long-lasting protection against the accidental scratches, scrapes and blemishes that eventually scar every wrist-worn watch. It is, in fact, nearly as hard as sapphire, itself second only to diamond in hardness.

    GMT stands for “Greenwich Mean Time”, also known as Coordinated Universal Time. A GMT watch has a 24-hour display complication that indicates a second time zone.

    A power reserve indicator is a complication of the watch, and shows the amount of remaining stored energy on an automatic watch.

    A tachymeter is a complication on a watch allowing the user to measure speed based on time traveled over a fixed distance.

    An automatic watch, also known as a self-winding watch, allows you to use your mechanical watch without having to wind it each day. Manual-winding watches are not self-winding and require you wind them by hand in order for the watch to operate.

    All the Zeiss lenses are constructed from impact-resistant prescription material featuring a scratch-resistant coating to prevent damages from normal use. However, no eyeglass lenses, not even glass lenses, are completely scratch proof.

    All our eyeglasses provide 100% UV protection and we recommend that sunglasses are worn whenever you are out in bright sunlight conditions.

    Not all the lenses are polarized as it is considered as an additional filter for specific needs and occasions. You can find this characteristic on the eyewear’s description.

    Yes, the bending of the temple tip can be adjusted on our acetate (plastic) and metal frames.

    Clean the eyewear with water or a mild detergent and with a soft cloth, preferably microfiber. Gently wipe the lens clean with the microfiber cloth rubbing in a circular motion.

    The frames are generally made with an alloy of nickel, copper and zinc; however, the coating and polishing process, which our metal frames go through, prevent from rusting / corrosion and make the frames hypo-allergenic and safe for all to wear.

    Clean the eyewear with water or a mild detergent and with a soft cloth, preferably microfiber. Gently wipe the lens clean with the microfiber cloth rubbing in a circular motion.

    Plastic material is heated and melted, then pressed towards an eyewear shape mould that can contain also metal. Injected material is lighter than acetate.


    Elasticity and flexibility are its main qualities. However, very stable, it will retain its form, therefore it is non-adjustable.

    Yes, it does come with a dedicated case.
