Seiko 4R15 Automatic Divers F.A.Q.

How do I wind my Seiko 4R15 Automatic Divers Watch?

The Seiko 4R15 movement is automatic, meaning it winds itself with the motion of your wrist. However, if the watch has stopped, you can manually wind it by turning the crown clockwise about 20 times while it is in its normal position.

What should I do if my Seiko 4R15 watch is running fast?

If your watch is running fast, it may need to be demagnetized. Exposure to magnetic fields can affect the accuracy of the timekeeping. If the problem persists, it is advisable to have it inspected by a professional watchmaker.

Can I manually set the date on my Seiko 4R15?

Yes, to set the date, pull the crown out to the first position and turn it clockwise until the correct date appears. Be careful not to set the date between 9 PM and 3 AM, as this can damage the date mechanism.

Is the Seiko 4R15 Divers Watch suitable for deep-sea diving?

The Seiko 4R15 is designed for recreational diving and is water-resistant up to 200 meters. For deep-sea diving, it is recommended to use a watch specifically designed for such depths.

How often should I service my Seiko 4R15 watch?

It is recommended to service your Seiko 4R15 watch every 3 to 5 years to ensure optimal performance and longevity. Regular servicing helps maintain its water resistance and movement accuracy.

What is the power reserve of the Seiko 4R15 movement?

The Seiko 4R15 movement has a power reserve of approximately 50 hours when fully wound. This means it can run for about two days without additional winding.

How can I test the water resistance of my Seiko 4R15?

To ensure water resistance, have your watch tested by a professional watchmaker regularly, especially after battery changes or repairs. Avoid exposing it to sudden temperature changes or chemicals that could compromise its seals.

Why does my Seiko 4R15 stop at night?

If your watch stops at night, it might not be getting enough wrist movement during the day to keep it fully wound. Try manually winding it or wearing it more consistently to maintain power.

Can I replace the strap on my Seiko 4R15 Divers Watch?
