Ma montre est-elle encore étanche ?

L'étanchéité indiquée au dos de la montre n'est valable que si les joints sont en bon état. Ils vieillissent avec le temps, la chaleur et les produits : seul un test permet de le vérifier.

Tous les combien faut-il tester l'étanchéité ?

Une fois par an si vous vous baignez avec votre montre, et après chaque ouverture du fond (pile, verre, révision).

L'étanchéité est-elle garantie ?

Nous testons l'étanchéité jusqu'à 10 bars, mais elle ne bénéficie pas d'une garantie. Une montre vintage, elle, n'est jamais garantie étanche : mieux vaut la garder loin de l'eau.

Frequently asked questions

Is my watch still water-resistant?

The water resistance marked on the caseback only applies if the gaskets are in good condition. They age with time, heat and chemicals: only a test can confirm it.

How often should water resistance be tested?

Once a year if you swim with your watch, and after every opening of the caseback (battery, crystal, service).

Is water resistance guaranteed?

We test water resistance up to 10 bar, but it isn't covered by a warranty. A vintage watch is never guaranteed water-resistant: it's best kept away from water.
