SERVICE/CARE

Are there replacement parts for my old Longines watch?

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.

How long is the lifetime of a watch battery?

Battery life varies usually from 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.

How much does it cost to service my watch?

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.

Where can I purchase additional links?

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

What should I do to ensure that my watch continues to provide excellent service for many years?

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.

How do I replace my battery?

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



TECHNICAL INFORMATION

Which recommendations should I follow to make sure that my Longines watch continues to function for many years to come?

  • 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 will never accumulate its full power reserve and may stop again a few hours after you remove it from your wrist. For your information, all Longines automatic movements have a safety system to prevent the over-winding of the mainspring. This means that you cannot damage the watch through winding. Due to technical reasons, a non-mechanical movement does not have this safety system. With such movements, you will feel a mechanical resistance when you have wound the watch completely. These movements can damage by over-winding.
  • 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.
  • Guarantee: always have your watch checked, serviced and repaired by an authorized Longines agent to maintain your guarantee 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.
  • Shocks: We recommend that you avoid every kind of shock. We manufacture all of our watches according to NIHS standards. This means that your watch should resist and continue to function after suffering a fall from one meter onto solid wood. Furthermore, it is important to note that a hard knock might cause the watch to lose its water-resistance without you realizing it.
  • Seawater: We recommend that you wash your watch with water after every dip in the sea

 

Up to which depths are Longines watches water-resistant and when should I check the water-resistance?

We create all of our watches according to the norms of the Swiss watchmaking industry (NIHS). All 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.

I just purchased a Conquest V.H.P., is there a manual to help me understand its features?

WATCHES

What is a watch movement?

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.

What is a quartz movement?

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

What is an automatic movement?

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, making manual winding unnecessary.

What is a chronograph?

A chronograph is an instrument for recording time.

What is a chronometer?

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

What is a rotating bezel?

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.

What is an E.O.L. indicator?

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, replace the battery immediately.

What is PVD?

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 close to that of outer space, 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.

What is a GMT watch?

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.

What is a power reserve indicator?

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

What is a tachymeter?

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

What is the difference between a self-winding and a manual-winding movement?

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.
