FAQs
How long does the Eco-Drive battery last?
The rechargeable light-powered cell in Eco-Drive watches typically lasts for many years (often 10 years or more) under normal use and charging conditions, and it is designed to be replaced by a service center when it eventually loses its capacity.
What does ISO compliant mean for a dive watch?
ISO 6425 compliance means the watch has met rigorous standards set for dive watches, ensuring its reliability for underwater use, including specific requirements for water resistance, shock resistance, magnetic resistance, and readability.
Can I wear this watch for everyday activities like swimming or showering?
Yes, the Promaster Diver is designed for water activities. Its 200m water resistance and durable construction make it suitable for swimming, showering, and most water sports. Always ensure the crown is fully pushed in.
How should I charge the watch if it has stopped?
Place the watch in direct sunlight or under a bright artificial light source for at least 8 hours, or until the second hand starts moving at regular intervals. Continuous light exposure will keep it charged.
Is the crystal scratch-resistant?
The watch features an anti-reflective mineral crystal. While durable, it is more susceptible to scratches than sapphire crystals. Avoid hard impacts and abrasive surfaces.
What is the purpose of the green unidirectional bezel?
The unidirectional rotating bezel is a critical safety feature for divers. It is used to track elapsed time underwater and can only be rotated counter-clockwise, preventing accidental changes that could shorten the perceived dive time.
Troubleshooting
Watch has stopped or is losing time.
Expose the watch to a strong light source for at least 8-10 hours to fully recharge the Eco-Drive battery. If the issue persists, contact customer support.
Date is not changing correctly.
Ensure the watch is correctly set. Pull the crown out to the first position and advance the hour hand past midnight to set the date. Avoid changing the date between 9 PM and 4 AM, as this can damage the movement.
Water resistance compromised (fogging under crystal).
Do not wear the watch in water. Contact an authorized service center immediately for inspection and sealing.
Bezel is stiff or difficult to turn.
Rinse the bezel area with fresh water and gently rotate it. If it remains stiff, avoid forcing it and seek professional servicing.
