Water resistance is a condition-dependent feature, not a permanent guarantee. Gaskets, crowns, case assembly, age and previous impacts can all change protection.
Before water exposure
Check that the crown and pushers are fully closed. Never operate the crown or chronograph pushers while the watch is wet.
Avoid heat and steam
Hot showers, saunas and rapid temperature changes can affect seals and create condensation.
Strap awareness
Leather straps can stain, stiffen or deteriorate after water exposure. Dry metal and rubber straps carefully.
After an impact
A hard knock can affect the case, crystal or seals. Stop exposing the watch to water until it has been checked.
Routine cleaning
Use a clean, soft, dry microfiber cloth. For crevices, use a soft dry brush with light pressure. Avoid solvents, aggressive chemicals and abrasive polishing products.
Condensation
If moisture or fog appears beneath the crystal, keep the watch away from further water exposure and seek service promptly. Persistent condensation can damage the movement and dial.
Storage and magnetism
Store the watch in a dry place away from strong magnetic sources. If an automatic or mechanical watch begins gaining or losing time unexpectedly, magnetism or impact may be a contributing factor.
