Full details
The Citizen Promaster Diver (BN0150-28E) is an ISO-compliant dive watch for recreational divers and outdoor enthusiasts who need a reliable, low-maintenance timepiece. Its key benefit is the Eco-Drive technology, which powers the watch using any light source, eliminating the need for battery changes. A potential caveat for some users might be the 42mm case size, which could be larger than preferred for those with smaller wrists.

FAQs
Does this watch require a battery change?
No, the Citizen Promaster Diver BN0150-28E features Eco-Drive technology, which is powered by light. It converts any natural or artificial light into energy, eliminating the need for battery replacements.
What does ISO-compliant mean for a dive watch?
ISO-compliant means the watch meets the international standard (ISO 6425) for dive watches, ensuring it has specific features and performance characteristics required for safe use underwater, such as water resistance, shock resistance, and magnetic resistance.
How long does the charge last if the watch is not exposed to light?
A fully charged Eco-Drive watch can run for several months (typically 4-6 months or more) in complete darkness. However, regular exposure to light is recommended to maintain optimal performance and longevity of the power cell.
Can I wear this watch for scuba diving?
Yes, this watch is rated for 200M water resistance and is ISO-compliant, making it suitable for scuba diving at depths that do not require helium escape valves.
How do I clean my Promaster Diver watch?
After exposure to salt water or chlorine, rinse the watch with fresh water. Clean the case and strap using a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the finish or seals.
What is the warranty period for this watch?
The watch comes with a 5-year Citizen UK warranty, providing coverage against manufacturing defects.
Is the rubber strap interchangeable?
Yes, the rubber strap can be replaced with a standard watch strap of the same lug width if desired, allowing for customization.
Troubleshooting
Watch stops running or loses time.
The Eco-Drive power reserve may be depleted. Expose the watch to a strong light source (preferably sunlight) for at least 8 hours to fully recharge the power cell. Ensure the watch is regularly exposed to light during normal wear.
Difficulty setting the time or date.
Unscrew the crown by turning it counter-clockwise. Gently pull the crown out to the appropriate position (usually two clicks for time, one for date). Set the time and date, then push the crown back in and screw it down clockwise to ensure water resistance.
Reduced water resistance or fogging under the crystal.
The screw-down crown may not be fully tightened, or the seals may be compromised. Ensure the crown is screwed down completely. If fogging persists or you suspect water ingress, do not operate the crown and seek professional service immediately to prevent internal damage.
Bezel is difficult to turn.
Debris or salt build-up can make the bezel stiff. Rinse the watch thoroughly with fresh water, paying attention to the bezel area. Gently try to rotate the bezel while rinsing. If the issue persists, avoid forcing it and consult a service center.

Setup, Compatibility & Care
Setup: The Promaster Diver BN0150-28E requires no complex setup. Its Eco-Drive technology means it is powered by light. Simply expose the watch to any light source (natural sunlight or artificial light) to charge it. A full charge can power the watch for several months in darkness. There are no batteries to change or electronic settings to configure initially, beyond setting the time and date.
Compatibility: This watch is compatible with standard watch strap replacements if you wish to change from the rubber strap. The movement itself is self-contained and does not require compatibility with external devices.
Care:
- Cleaning: Rinse the watch with fresh water after exposure to salt water or chlorine. Clean the case and strap with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Crown: Ensure the screw-down crown is fully tightened after setting the time or date to maintain water resistance. If diving or exposing the watch to water, always check that the crown is securely fastened.
- Charging: While the watch is designed to run continuously, avoid storing it in complete darkness for extended periods. Regular exposure to light, even indoors, is sufficient to keep the Eco-Drive system functioning optimally.
- Maintenance: Beyond cleaning, the watch typically requires servicing only if issues arise, as there are no user-serviceable parts like batteries. Refer to the warranty for service details.
