Full details

The Citizen Promaster Diver (BN0267-04L) is an ideal choice for outdoor enthusiasts and professional divers who require a reliable, ISO-compliant timepiece that transitions seamlessly from underwater use to daily wear. Its standout benefit is the Eco-Drive technology, which eliminates the need for battery changes by charging in any light, though the 40.6mm case size may feel substantial for those with smaller wrist profiles.

How do I care for the strap?

Can I replace the strap?

Troubleshooting

Watch has stopped running

Expose the dial to direct sunlight or a bright artificial light source for several hours to recharge the Eco-Drive capacitor.

Date is incorrect

Pull the crown out to the first click position and rotate clockwise to advance the date to the current day.

Bezel is hard to rotate

Rinse the watch thoroughly in fresh, lukewarm water to remove accumulated salt or grit that may be blocking the rotation mechanism.

Pros and Cons

Pros

  • Battery-free operation via Eco-Drive
  • ISO-compliant professional diver specification
  • High-contrast luminous dial for excellent readability
  • Scratch-resistant sapphire crystal
  • Water-resistant up to 200 metres

Cons

  • 40.6mm case size may be bulky for some users

Setup, Compatibility & Care

To ensure optimal performance, keep the watch face exposed to light regularly to maintain a full power reserve. When setting the date and time, unscrew the crown carefully if applicable to access the setting positions. For water activities, always ensure the crown is fully pushed in and, if screw-down, tightened completely before submersion. Clean the watch after saltwater exposure by rinsing it with fresh water to prevent salt buildup on the bezel and strap. Avoid harsh chemicals or solvents that could damage the blue finish of the strap or the casing.
