NH34 Movement Setup Guide: Date, GMT Hand & Time

How to Set Up and Use Your NH34 Movement Watch

The NH34 is an automatic GMT movement designed for everyday use. It features manual winding, automatic winding through wrist movement, a date function, and an independent 24-hour GMT hand for tracking a second time zone.

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. Move the hands to a safe time before adjusting the date — 6:00 is recommended.
4. Set the correct date.
5. Set the GMT hand if needed.
6. Set the correct local time.
7. Push the crown back in securely.
8. 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 NH34 watch uses three crown positions:

• Position 0: Crown secured / normal position
• Position 1: Manual winding
• Position 2: Date setting and GMT hand setting
• Position 3: Time setting

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

At the date and GMT setting position:

• turning the crown counterclockwise adjusts the date
• turning the crown clockwise adjusts the GMT hand

How to Wind the Watch

The NH34 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 NH34 has an approximate 41-hour power reserve when fully wound.

Wind the crown gently and never force it

How to Set the Date

The NH34 includes a date function that must be adjusted with care.

Important: Do not change the date while the watch is in its automatic date-change period, usually between 9:00 PM and 3:00 AM. Adjusting the date during this period can damage the movement.

To set the date safely:

1. If your watch has a screw-down crown, unscrew it first.
2. Pull the crown out to Position 2.
3. Before changing the date, make sure the watch is showing a safe time such as 6:00.
4. Turn the crown counterclockwise until the correct date appears.

How to Set the GMT Hand

The NH34’s GMT hand allows you to track a second time zone on a 24-hour scale.

To set the GMT hand:

1. With the crown still in Position 2, turn the crown clockwise.
2. Move the GMT hand until it points to the correct hour for your chosen second time zone.
3. Use the 24-hour scale to distinguish day and night in that reference time zone.

This allows the watch to display local time with the main hands and a second time zone with the GMT hand.

How to Set the Time

To set the local time:

1. If your watch has a screw-down crown, unscrew it first.
2. Gently pull the crown out to Position 3.
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 local time.
5. To confirm AM or PM, advance the hands past 12 o’clock and watch when the date changes. If the date changes, the watch has passed midnight.
6. Once the correct time is set, push the crown back in.
7. 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 date if needed
3. Set the GMT hand if needed
4. Set the correct local time
5. 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 watch
• If your watch has a screw-down crown, always screw it down properly after use
• Never force the crown when winding, setting the date, setting the GMT hand, or setting the time
• Avoid changing the date between 9:00 PM and 3:00 AM
• 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 NH34 is designed to be practical, dependable, and easy to live with. Wind it when needed, wear it regularly, and use the GMT hand when you want a second time zone at a glance.
