Key Technologies

Eco-Drive Technology

Citizen's proprietary Eco-Drive technology harnesses the power of light from any source, converting it into energy stored in a permanently rechargeable power cell. This eliminates the need for battery replacement, offering convenience and reducing environmental impact.

A fully charged Eco-Drive watch can run for months, even in complete darkness, thanks to its power reserve indicator and energy-saving functions. This ensures reliable operation without constant exposure to light.

Atomic Timekeeping

The Promaster Air Skyhawk A-T features atomic timekeeping, which automatically synchronizes with atomic clocks in 43 world cities. This ensures unparalleled accuracy, with the watch being precise to one second over 20 million years.

The watch receives time signals from transmitting towers, ensuring that the time and date are always accurate, even across different time zones.

Super Titanium™ Construction

Citizen's Super Titanium™ is a proprietary material that is five times harder and 40% lighter than stainless steel. This advanced material provides superior scratch resistance, enhanced comfort, and is gentle on the skin due to its hypoallergenic and rust-resistant properties.

Maintenance

Proper care and maintenance will ensure the longevity and optimal performance of your Citizen Promaster Air Skyhawk watch.

• Charging: Ensure the watch is regularly exposed to light to maintain its charge. Avoid prolonged storage in dark places. The power reserve indicator will help monitor the charge level.
• Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dirt and smudges. For water-resistant models, a damp cloth can be used, followed by drying.
• Water Resistance: The watch is water resistant to 200 meters. This makes it suitable for swimming and snorkeling, but not for deep-sea diving unless specified. Always ensure the crown is pushed in completely before exposing the watch to water. Avoid operating buttons underwater.
• Temperature Extremes: Avoid exposing the watch to extreme temperatures, both hot and cold, as this can affect its performance and battery life.
• Chemicals: Keep the watch away from chemicals, solvents, and strong detergents, which can damage the case, band, or seals.

Troubleshooting

If you encounter any issues with your watch, refer to the following common troubleshooting tips:

• Watch Not Running/Low Power: If the watch stops or the hands move erratically, it may be due to insufficient charge. Place the watch under a bright light source (natural or artificial) for several hours to fully charge it.
• Incorrect Time/Date: Ensure the watch is receiving atomic time signals. Try placing it near a window overnight. If the issue persists, perform a manual time synchronization as described in the "Setup and Operating Instructions" section or consult the full user manual for detailed adjustment procedures.
• Hands Not Aligning: In rare cases, the watch hands may become misaligned. This can usually be corrected by performing a manual reset or hand alignment procedure. Refer to the comprehensive user manual for specific steps.
• Digital Display Issues: If the digital display is blank or showing incorrect information, ensure the watch is adequately charged. A full reset might be necessary, which is detailed in the user manual.
