Care Guide
- Wipe the stainless steel case and bracelet regularly with a soft, lint-free cloth to remove fingerprints, perspiration, and daily residue.
- After exposure to saltwater or chlorinated water, rinse the watch with fresh water and dry thoroughly with a soft cloth.
- Ensure the screw-lock crown is fully secured before any water exposure to maintain the 100-metre water resistance rating.
- Avoid operating the chronograph pushers or crown whilst the watch is submerged or wet, as this can compromise water resistance.
- Store your Edifice in a cool, dry place away from direct sunlight, strong magnetic fields, and extreme temperature fluctuations when not being worn.
- Have the water resistance gaskets inspected every 2-3 years, particularly if you frequently expose the watch to water, to ensure continued protection.
- Avoid impact or dropping the watch, as this can affect the quartz movement's accuracy and damage the mineral crystal.
- When the battery requires replacement, have this performed by an authorised service centre to ensure proper resealing and water resistance testing.
- If the bracelet becomes loose or links require adjustment, visit Cassim & Co. for professional sizing and maintenance.
