International Warranty
La Compagnie des Montres Longines, Francillon S.A. grants you, with effect from the purchase date, a twenty-four (24) month warranty on all LONGINES® watches models and a five (5) year warranty on mechanical watches purchased from January 1, 2021, under the terms set out in this warranty. All watch straps and bracelets are covered by a 24-month international warranty for any material or manufacturing defects. The LONGINES international warranty covers defects in materials and manufacturing that exist at the time of delivery of the LONGINES watch purchased ("defects"). The warranty takes effect only if the warranty certificate has been dated and fully completed by an official LONGINES dealer (“valid warranty certificate”). During the term of the warranty and on presenting the valid warranty certificate, you are entitled to have any defect repaired free of charge. In the event that repairs cannot restore your LONGINES watch to full working order, La Compagnie des Montres Longines, Francillon S.A. undertakes to replace it with an identical LONGINES watch or another LONGINES watch with similar characteristics. The warranty for the replacement watch expires on the same date as the warranty for the replaced watch.
The warranty does not cover:
- Battery life.
- Normal wear and tear (such as scratches on the case and/or glass; alteration of the colour and/or material of cases, straps, bracelets and chains made of leather, textile, rubber or any other non-metallic material; the PVD coating; the colour of bronze).
- Damage to any part of the watch resulting from unsuitable/improper use, neglect, carelessness, accidents (knocks, dents, crushing, scratches when changing the strap/bracelet, etc.), incorrect use of the watch, or failure to follow the instruction manual.
- Harm of any nature whatsoever resulting directly or indirectly from using the LONGINES watch or from any operational failure, defect or lack of precision in the watch.
- A LONGINES watch handled by a non-approved person (for example, for the purposes of replacing the battery or carrying out servicing or repairs) or having been altered from its original state other than under the supervision of La Compagnie des Montres Longines, Francillon S.A.
Any other claims against La Compagnie des Montres Longines, Francillon S.A., for example for any kinds of damage or harm other than those set out in this warranty, are expressly excluded, excepting statutory rights that the purchaser can assert against the manufacturer.

Precautions Concerning Water-Resistance
A watch's water-resistance can be affected by changes caused by the gaskets drying out, or an accidental shock to the crown. To help maintain your watch's water-resistance, we recommend rinsing it in soft water after any contact with sea water and having its water-resistance checked once a year by an approved LONGINES Service Centre. In no circumstances should you open your watch yourself.
IMPORTANT! Never activate the time-setting crown and/or push-pieces when the watch is underwater, and ensure that the crown and push-pieces are pushed in or screwed down before any immersion in water.
| Marking on the case-back | Meaning* |
|---|---|
| None | Not water-resistant |
| 3 bar | Water-resistant up to an overpressure of 3 bar (30 m)* |
| 5 bar | Water-resistant up to an overpressure of 5 bar (50 m)* |
| 10 bar | Water-resistant up to an overpressure of 10 bar (100 m)* |
| 30 bar | Water-resistant up to an overpressure of 30 bar (300 m)* |
*The water-resistance values indicated in metres are equivalent to the overpressure applied under standard ISO 22810.

Screw-in crown
Some LONGINES models are fitted with a screw-in crown which must be unscrewed before setting the time, correcting the date or winding. After setting the time or winding, return the crown to position 1, then push it back in and screw it in firmly in order to ensure the watch's water-resistance.
Setting the time
Pull the crown out to position 3 when the seconds hand is at 60. Turn the crown forwards or backwards until the desired time is displayed. Once the time is correctly set, push the crown back in to position 1.
Quick date correction
Do not attempt quick correction of the date between 8 p.m. and 3 a.m.
Pull the crown out to position 2 and turn it forwards to correct the date. While you are doing this, your watch continues to operate and so the time does not need resetting. The date needs correcting after any month with fewer than 31 days. Push the crown back in to position 1. The date changes when the hour hand passes midnight.
