How to Set Up Your Seiko NH72 Movement Watch: A Complete Guide

The Seiko NH72 movement is a beautiful, skeletonized automatic movement known for its mechanical design and reliability. While its transparent construction showcases the intricacies of the movement, setting it up is straightforward. In this guide, we’ll walk you through the steps to power up the movement and set the time on your NH72-powered watch.

Powering Up the NH72 Movement

The Seiko NH72 movement is an automatic movement, which means it powers itself through the natural motion of your wrist. However, if the watch has stopped or you want to ensure it’s fully wound, you can also manually wind it. Here's how:

1. Unscrew the Crown (if applicable): If your watch features a screw-down crown, begin by unscrewing the crown by rotating it counterclockwise until it releases and pops out to the winding position.
2. Manual Winding: Once the crown is in the winding position (first position closest to the case), rotate the crown clockwise (away from you) about 20 to 30 times. You will feel some resistance as the mainspring winds up. This manual winding is enough to give the NH72 movement approximately 40 hours of power reserve. Once fully wound, the watch will automatically recharge through wrist movement.
3. Wear the Watch Regularly: After winding, wearing the watch will keep it powered, as the rotor inside the NH72 movement continues to wind the mainspring with your wrist's motion. If you wear the watch daily, it will remain fully charged without the need for manual winding.

Setting the Time on Your NH72 Movement Watch

Once the watch is powered, it’s time to set the correct time. Here’s how to do it:

1. Pull the Crown to the Second Position: After unscrewing the crown (if applicable), gently pull it out to the second position. This is the time-setting position, and you should feel a distinct second click as you pull the crown. The NH72 movement features a hacking function, so the seconds hand will stop moving, allowing you to set the time accurately.
2. Adjust the Time: Turn the crown in either direction to move the hour and minute hands to the desired time. Be mindful of the AM/PM setting if your watch has a 12-hour dial. The NH72 movement doesn’t feature a date complication, so you don’t need to worry about avoiding certain hours when setting the time.
3. Push the Crown Back In: Once the correct time is set, gently push the crown back to its original position. If your watch has a screw-down crown, screw it back in by turning it clockwise to ensure the watch remains water-resistant.

Final Tips for Your NH72 Movement Watch

• Wind Regularly if Not Worn: If you don’t plan on wearing your watch every day, wind it every few days to keep it powered.
• Avoid Over-Winding: Although the NH72 movement has protection against over-winding, it’s still a good practice to wind the watch gently.
• Use a Watch Winder for Storage: If you own multiple watches and rotate them often, consider using a watch winder to keep your NH72 movement running smoothly when not in use.
