Full details
The Citizen Promaster Air Navihawk is designed for pilots, aviation enthusiasts, and anyone appreciating a robust, feature-rich timepiece. Its key benefit is the Eco-Drive technology, ensuring perpetual power from light without battery changes, complemented by a practical slide-rule bezel for flight calculations.

Extended Product Information
FAQs
How often does the Citizen Promaster Air Navihawk need to be charged?
Once fully charged, the watch can run for approximately 6 months in darkness. It is best to expose it to light regularly to maintain optimal performance and prevent it from stopping.
What is the purpose of the slide-rule bezel?
The slide-rule bezel allows pilots and enthusiasts to perform various calculations related to flight, such as speed, distance, fuel consumption, and multiplication/division, using a logarithmic scale.
Is the strap easily replaceable?
Yes, the watch typically uses a standard lug width, allowing for replacement with various compatible watch straps. However, for optimal fit and aesthetics, using the original or a recommended replacement is advised.
How do I reset the chronograph?
After using the chronograph, press the lower pusher to return the hands to zero. Ensure all chronograph hands are aligned at the 12 o'clock position when not in use; if not, a reset procedure might be necessary, often involving pulling the crown out to the furthest position.
What does 200-meter water resistance mean?
A 200-meter water resistance rating means the watch is suitable for swimming and recreational diving. However, it's important to note that this rating refers to static pressure and not actual diving depth. Always ensure the crown is screwed down before water exposure.
Is the sapphire crystal scratch-proof?
Sapphire crystal is highly scratch-resistant, making it very difficult to scratch under normal wear conditions. However, it can still be chipped or shattered under significant impact.
Troubleshooting
Watch stopped running
The watch may need charging. Expose it to a light source for several hours. If the issue persists after charging, consult the user manual for specific Eco-Drive troubleshooting.
Second hand is jumping in two-second intervals
This indicates a low power reserve. Charge the watch fully by exposing it to light.
Date is not changing correctly
Ensure the time is set between 9 AM and 5 PM to allow the date to change automatically. If set incorrectly, adjust the time by pulling the crown out to the appropriate position and setting it again, avoiding the date change period.
Bezel is stiff or difficult to turn
Clean the bezel area gently with a soft brush and mild soap if necessary, then rinse and dry thoroughly. Avoid forcing the bezel.

Setup, Compatibility & Care
Initial Setup:
- Charging: Expose the watch to a light source (natural or artificial) for several hours until the second hand moves. For best results, leave it under direct sunlight for a day or in front of a fluorescent lamp for a few days.

Care Instructions:
- Cleaning: Wipe the watch case and bracelet with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Water Resistance: While rated for 200m, it is recommended to rinse the watch with fresh water and dry it thoroughly after exposure to saltwater or chemicals like chlorine. Ensure the crown is screwed down before exposure to water.
- Storage: If storing the watch for an extended period, charge it fully and store it in a dark place. Periodically expose it to light to maintain the charge.
- Bezel: Keep the slide-rule bezel clean to ensure smooth operation.
