Maintenance

Cleaning

Regularly clean your Apple Watch Ultra 3 to maintain its appearance and functionality. Use a soft, lint-free cloth. If necessary, slightly dampen the cloth with fresh water. Avoid using abrasive materials, harsh chemicals, or compressed air.

Water Resistance

The Apple Watch Ultra 3 is water resistant to 100 meters under ISO standard 22810:2010. It is suitable for recreational scuba diving to 40 meters and high-speed water sports. After exposure to chlorinated water, salt water, or muddy environments, rinse the watch with fresh water and dry it thoroughly.

Battery Care

To optimize battery longevity, avoid extreme temperatures. While the watch supports fast charging, prolonged exposure to high temperatures during charging can degrade battery health over time. For extended storage, charge the watch to approximately 50% and store it in a cool, dry place.

Troubleshooting

Watch Not Turning On or Responding

Band Installation Difficulty

If the band does not slide in smoothly, ensure it is correctly oriented and aligned with the watch case slots. Do not force the band. If issues persist, inspect the band and watch case for any obstructions or damage.
