3.3 Water Resistance

This watch is water resistant to 100 meters (10 bar). This means it is suitable for swimming and snorkeling, but not for scuba diving. Ensure the crown is pushed in completely before exposing the watch to water. Do not operate the crown or pushers while the watch is wet or submerged.

4. Maintenance

4.1 Cleaning Your Watch

Wipe the watch case and bracelet periodically with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by a dry cloth. Avoid using chemical cleaners or abrasive materials.

4.2 Battery Replacement

The watch is powered by a lithium metal battery. When the battery runs low, the watch may exhibit irregular movement or stop. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

4.3 Periodic Inspection

It is recommended to have your watch inspected by an authorized Seiko service center every 2-3 years to check the gaskets, water resistance, and overall movement condition.

5. Troubleshooting

• Watch not running: Check if the crown is pushed in completely. If the watch still does not run, the battery may need replacement.
• Chronograph hands do not reset to zero: This may require a chronograph hand position adjustment. Consult the full instruction manual or a service center.
• Condensation inside the crystal: This indicates a loss of water resistance. Immediately take the watch to a service center to prevent further damage.
