DETERMINING 12 AM MIDNIGHT

1. Pull out the crown to the 2nd position.

2. Rotate the crown clockwise (forward) to advance the hour and minute hands until the date changes, which indicates 12 AM midnight.

3. Keep rotating the crown clockwise to set the hour and minute hands to the exact time.

4. Push the crown back in to the normal crown position.

(Now that you’ve established AM/PM you can change the date as needed. Do not change the date between 8:00 PM (20:00) and 3:00 AM (03:00) as this may damage the functionality and operation of the calendar.)

 

Mechanical watch movements are intricate micro-machines built to exacting standards. To ensure that your watch operates with perfect precision for many years to come, please familiarize yourself with the following:

 

Accuracy: The average accuracy tolerance for the NH35 movement is around -20/+40 seconds per day under normal operating conditions. Accuracy depends very much on the regulation done on the watch during the assembly, the power reserve contained in the watch, the natural hand motion of the user, and the external factor such as a shock or drop.

 

Service Intervals: As with most precision machines, an automatic watch must be serviced regularly to maintain peak performance. We recommend that you have your watch professionally serviced every 5 years. A shorter service interval may be required depending on the climate and conditions the watch is exposed to.

SETTING THE DATE

1. Pull out the crown to the 1st position (first pull out after you unscrew the crown)

2. Rotate the crown anti-clockwise (backward) to set the date.

3. Push the crown back in to the zero position and screw in back the crown.

 

Important: Do not change the date between 8:00 PM (22:00) and 3:00 AM (03:00) as this may damage the functionality and operation of the calendar.

SETTING THE TIME

1.  Pull out the crown to the 2nd position.

2.  Rotate the crown to set the hour and minute hands.

3.  Push the crown back in to the zero position and screw in back the crown.

HACKING THE SECOND HAND

The second hand can be stopped to synchronize the time to another reference time.

1. To stop the second hand, pull out the crown to the 2nd position (the time setting position).

2. Push the crown back in to the normal crown position when ready to synchronize.

WINDING THE MAINSPRING BY SIMPLY WEARING THE WATCH

By simply wearing the watch on your wrist, the mainspring is wound automatically as a result of the natural motion of your arm.

WINDING THE MAINSPRING MANUALLY

Sometimes the wearer does not move much so manually winding the watch by rotating the crown clockwise (forward) 10-15 times in the zero crown position (the position after the crown has been unscrewed) and shaking/swirling the watch slightly, will help increasing the power reserve of the watch.
