FAQs

What is the water resistance rating?

While it is a robust timepiece, please check the case back for specific bar/meter ratings to confirm its suitability for swimming or diving.

Does this watch require a battery?

No, this is an automatic watch powered by the movement of your wrist and the tension stored in the mainspring.

Can I replace the strap?

Yes, the watch features standard lugs, allowing you to swap the stainless steel bracelet for a leather or rubber strap that complements the motoring theme.

What does the 6R55 movement offer?

The 6R55 is a high-performance Seiko caliber known for its 72-hour power reserve and consistent accuracy.

Is the crystal truly scratch-resistant?

The watch uses sapphire crystal, which is the most scratch-resistant material commonly used in watchmaking.

Troubleshooting

Watch has stopped running

Manually wind the movement by rotating the crown 20-30 times clockwise to restore the power reserve.

Time is running fast or slow

Check if the watch was recently exposed to a strong magnetic source and consult a professional watchmaker for demagnetization if necessary.

Difficulty reading time in the dark

Expose the watch face to a bright light source for a few minutes to 'charge' the Lumibrite markers.

Setup, Compatibility & Care

To keep your Seiko Speedtimer in top condition, ensure the crown is fully pushed in after setting the time to maintain water resistance. Avoid exposing the watch to strong magnetic fields, which can impact the accuracy of the automatic movement. For routine care, use a soft, dry cloth to wipe away perspiration or debris from the stainless steel case and crystal. If the watch has been stationary for more than three days, give the crown 20-30 clockwise rotations to fully tension the mainspring before setting the time.
