NH38 Movement Setup Guide: Wind & Set the Time

How to Set Up and Use Your NH38 Movement Watch

The NH38 is a reliable automatic movement designed for simple, everyday use. It features manual winding, automatic winding through wrist movement, and a hacking function for precise time setting.

If your watch has stopped or you are wearing it for the first time, follow the steps below to get it running and set correctly.

Before First Wear

Before wearing your watch for the first time, it is best to give it a manual wind so the movement has enough power to start properly.

1. If your watch has a screw-down crown, unscrew it by turning it counterclockwise until it releases.
2. With the crown in its normal winding position, turn it clockwise 20 to 30 times.
3.  Pull the crown out to the time-setting position and set the correct time.
4. Push the crown back in securely.
5. If your watch has a screw-down crown, screw it back down completely to maintain water resistance.

Once this is done, normal wrist movement will continue to wind the watch during wear.

Crown Positions

Your NH38 watch uses simple crown positions:

• Position 0: Crown secured / normal position
• Position 1: Manual winding
• Position 2: Time setting

If your watch has a screw-down crown, you must first unscrew it before using any crown function.

How to Wind the Watch

The NH38 is an automatic movement, which means it winds itself while worn. It can also be wound manually when needed.

To manually wind the watch:

1. Make sure the crown is in the normal winding position.
2. Turn the crown clockwise 20 to 30 times to give the movement enough energy to start running.
3.  Once the watch is on your wrist, normal movement will continue to build and maintain power.

The NH38 has an approximate 41-hour power reserve when fully wound.

How to Set the Time

To set the time:

1. If your watch has a screw-down crown, unscrew it first.
2. Gently pull the crown out to Position 2.
3. The seconds hand will stop. This hacking function allows for more precise time setting.
4. Turn the crown to move the hands to the correct time.
5. Push the crown back in once the time is set.
6. If your watch has a screw-down crown, screw it back down fully.

Always handle the crown gently and never force it.

If the Watch Has Stopped

If your watch stops after being left unworn, this is normal.

Automatic watches rely on stored energy or regular wrist movement to keep running. If the power reserve is depleted:

1. Wind the crown clockwise 20 to 30 times
2. Set the correct time
3. Wear the watch as usual

After that, normal wrist movement should keep it running.

Care and Good Habits

A few simple habits will help keep your watch running well:

• If the watch is not worn regularly, wind it manually from time to time
• Always push the crown back in securely after setting the time
• If your watch has a screw-down crown, always screw it down properly after use
• Never force the crown when winding or setting
• Have the watch serviced periodically to maintain performance over time

As a general guideline, mechanical watches benefit from servicing every 3 to 5 years, depending on wear and use.

A Final Note

The NH38 is designed to be simple, dependable, and easy to live with. Wind it when needed, wear it regularly, and it will do the rest.
