FAQs

How do I wind the watch?

The watch winds automatically with wrist movement. You can also manually wind it by turning the crown clockwise when the crown is in the closed position. Wind it about 20-30 times.

How long is the power reserve?

The watch has a power reserve of up to 72 hours when fully wound.

Is the strap replaceable?

Yes, the leather strap can be replaced with another strap of the appropriate size.

What kind of crystal does the watch have?

The watch features scratch-resistant sapphire crystal.

What is the water resistance rating?

The watch is water-resistant to 200 meters.

How do I use the compass function?

While the watch has a compass function, it's primarily for reference. Align the hour hand with the sun, and the direction of the "12" on the dial will point to the north direction. More accurate readings will require additional tools.

What should I do if the watch fogs up?

If moisture appears inside the watch, it indicates a breach in water resistance. You should take it to a Seiko-authorized service center immediately to prevent damage to the movement.

Troubleshooting

Ensure the watch is fully wound (at least 72 hours of power reserve), or wear the watch regularly to keep it wound. If the problem persists, the watch may need servicing.

GMT hand is not working correctly.

Check that the GMT hand is properly aligned with the 24-hour bezel. If not, reset the hand according to the manual.

Water has entered the watch.

Immediately take the watch to a Seiko-authorized service center.
