Setting the Date:

- Rotate the crown clockwise or counter-clockwise (depending on the movement) until the correct date appears in the date window.
- Push the crown back into position 0.

Chronograph Hand Reset:
If the chronograph hands (seconds, minutes) do not reset to the zero position after use, they may need calibration.

Maintenance
Cleaning Your Watch:
To maintain the appearance of your watch, regularly wipe the case and strap with a soft, dry cloth. For water-resistant models, a slightly damp cloth can be used, followed by drying. Avoid using chemical cleaners, as they can damage the watch's finish or seals.
Battery Replacement:
Your watch is powered by a CR2 battery. When the battery runs low, the watch may stop or the second hand may skip intervals. Battery replacement should be performed by a qualified watch technician to ensure the watch's water resistance and proper function are maintained.
