• Method:
  1. Prepare a solution of warm water and mild soap
  2. Use a soft brush (e.g., soft toothbrush) to gently clean the case and bracelet
  3. Rinse thoroughly with clean water
  4. Dry with a soft, lint-free cloth
• Crystal Care: Use a microfibre cloth for the crystal to avoid scratches
• Bezel Cleaning: Pay special attention to the bezel, ensuring no debris impedes its rotation

Note: Always ensure the crown is fully screwed down before exposing the watch to water.

1. Water Resistance: Maintaining and Testing

Despite the Hydroconquest's impressive water resistance, regular maintenance is crucial:

• Gasket Check: Have gaskets checked annually by a professional
• Crown and Pushers: Ensure they're fully screwed down before water exposure
• Post-Dive Care: Rinse with fresh water after exposure to saltwater or chemicals
• Professional Testing: Have water resistance professionally tested every 1-2 years
• Signs of Compromise: If you notice any fogging under the crystal, seek immediate professional attention

Remember, water resistance can deteriorate over time, so regular checks are essential, especially if you use your Hydroconquest for diving.

1. The Automatic Movement: Care and Considerations

For automatic Hydroconquest models, movement care is crucial:

• Regular Wear: Wear your watch regularly to keep the movement active
• Manual Winding: If unworn for a while, wind manually before wearing
• Position When Unworn: Store flat or crown-up to optimise positional accuracy
• Accuracy Monitoring: Check accuracy periodically; significant deviations may indicate service needs
• Overwind Protection: Modern automatics have this, but avoid excessive manual winding

Understanding these aspects helps maintain the heart of your Hydroconquest - its movement.

1. Bracelet and Strap Maintenance

The bracelet or strap is an integral part of your Hydroconquest:
