La Grande Classique - 20mm

The La Grande Classique collection is inspired by the Agassiz model created in 1982 to celebrate Longines' 150th anniversary, embodying the brand's classic elegance.

The 20mm dial size offers a slim and elegant profile, characteristic of the collection. It is designed to be understated, but individuals preferring larger watch faces might find it on the smaller side.

Water resistance specifications vary by model. Consult the specific details for your La Grande Classique watch. Generally, models with a slim profile are not designed for extensive water activities like swimming or diving.

Gently polish the watch with a soft, dry microfiber cloth. For persistent marks, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners.

The La Grande Classique collection typically features high-quality Swiss quartz or mechanical movements, depending on the specific reference.

Servicing should be performed by an authorized Longines service center or a qualified watchmaker experienced with luxury timepieces to ensure proper care and maintenance.

If automatic, ensure it is being worn regularly. If manual, wind the crown. For quartz models, the battery may need replacement by a professional.

For mechanical watches, regular servicing might be required. For quartz watches, ensure the battery is fresh. Extreme temperatures can also affect accuracy.

Check the clasp and any extension links. If damage is suspected, consult an authorized Longines service center for repair or replacement.

Do not force the crown. It may require professional lubrication. Ensure it is properly aligned before attempting to set the time or date.
