• Main Dial: Displays hours, minutes, and seconds.
• Sub-dial (9 o'clock position): 24-hour indicator.
• Sub-dial (6 o'clock position): Date indicator.
• Sub-dial (3 o'clock position): Day of the week indicator.

4. Setup

4.1 Setting the Time

1. Pull the crown out to the second click position. The second hand will stop.
2. Rotate the crown to move the hour and minute hands to the desired time. Ensure the 24-hour sub-dial also reflects the correct AM/PM period.
3. Push the crown back in to the normal position. The second hand will resume movement.

4.2 Setting the Date and Day

The date and day indicators change automatically once every 24 hours. If the date changes during the day, it means the time is set for PM instead of AM. Adjust the time accordingly.

• Quick Adjustment:
  Press Pusher A (above crown) to advance the day of the week.
  Press Pusher B (below crown) to advance the date.
• Note: Avoid adjusting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism. If adjustment is necessary during this period, first advance the time past 1:00 AM, then set the date, and finally reset the time.

4.3 Adjusting the Metal Band

The metal band may require adjustment to fit your wrist comfortably. This typically involves adding or removing links. It is recommended to have this adjustment performed by a qualified jeweler or watch technician to prevent damage to the band or watch.

• The sub-dial at the 9 o'clock position indicates the current hour in a 24-hour format, synchronizing with the main hour hand.
• The sub-dial at the 6 o'clock position displays the current date (1-31).
• The sub-dial at the 3 o'clock position indicates the current day of the week (e.g., SUN, MON, TUE).

6. Maintenance

This watch is marked as "WR 50M" (Water Resistant 50 meters). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown or pushers while the watch is wet or submerged.
