1. Unscrew the lower crown: Turn the lower crown counter-clockwise until it springs free.
2. Set the Date (Position 1): Gently pull the crown out to the first click (Position 1). Turn the crown counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement. If the current time falls within this period, first adjust the time outside this range, then set the date, and finally reset the time.
3. Set the Time (Position 2): Pull the crown out to the second click (Position 2). The second hand will stop. Turn the crown to adjust the hour and minute hands. To ensure accurate time, set the minute hand a few minutes past the desired time, then turn it back.
4. Synchronize Time: Once the correct time is set, push the crown back into Position 0 when a time signal (e.g., from a radio or phone) reaches the 12 o'clock position.
5. Secure the crown: Push the crown back in and screw it clockwise tightly against the case until it is fully seated. This is crucial for maintaining water resistance.
