FAQs

What is the power reserve of the Hamilton Khaki Navy Frogman?

The watch is powered by the Hamilton H-10 automatic movement, which offers an impressive 80-hour power reserve.

Is this watch suitable for professional diving?

Yes, with a water resistance rating of 300 meters and a unidirectional diver's bezel, it is engineered for professional underwater use.

How do I set the time and date?

Pull the crown out to the first position to set the date (if applicable to your specific sub-model) and to the second position to set the time. Ensure the crown is screwed down after setting.

What is the material of the watch crystal?

The watch features a scratch-resistant sapphire crystal for enhanced durability and clarity.

Does the watch need a battery?

No, this is an automatic watch powered by the movement of your wrist or manual winding. It does not use a battery.

How should I care for the rubber strap?

Rinse the rubber strap with fresh water after exposure to saltwater or chlorine. Clean with a soft, damp cloth. Avoid harsh chemicals.

What does the PVD coating do?

The Black Physical Vapor Deposition (PVD) coating provides a durable, wear-resistant, and aesthetically dark finish to the stainless steel case.

Troubleshooting

Watch has stopped running

Shake the watch gently for 30 seconds or wind the crown manually about 30-40 turns. Ensure the watch has been worn consistently to maintain the power reserve.

Inaccurate timekeeping

Automatic watches can have a variance of +/- seconds per day. If significantly off, ensure it's fully wound and consider a professional service if the issue persists.

Difficulty operating the crown

Ensure the crown is fully unscrewed before attempting to adjust the time or wind the watch. If it feels stiff, do not force it; seek professional assistance.

Condensation under the crystal

This indicates a potential breach in water resistance. Remove the watch from moisture immediately and take it to an authorized service center for inspection and sealing.

Care:

After Saltwater Use: Always rinse the watch with fresh, clean water after exposure to saltwater to prevent corrosion.
Cleaning: Use a soft, damp cloth to clean the case and crystal. Avoid abrasive cleaners or solvents.
Crown: Ensure the crown is securely pushed in or screwed down (depending on the model's specific lock system) to maintain water resistance.
Servicing: Automatic watches benefit from professional servicing every 3-5 years to ensure continued accuracy and longevity.
