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.

    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.  

    The Longines museum explores over 180 years of watchmaking history and is open to the public on working days from 9 a.m. to 12 p.m. and 1.30 p.m. to 5 p.m.

    During a 90 minute guided tour, visitors can discover the brand's main watches, navigational instruments and timing devices, as well as a range of exceptional photographs, posters, films, medals and archival records.
