2.3 Setting the Date
- Pull the crown out to position 1.
- Rotate the crown either clockwise or counter-clockwise (depending on the movement) until the correct date appears in the date window.
- Once the date is set, push the crown back into position 0.
- Note: Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism. If the date needs adjustment during this period, first set the time outside this range, adjust the date, then reset the time.
3. Operating the Chronograph
The chronograph function allows you to measure elapsed time independently of the main time display.
- Starting the Chronograph: Press the upper pusher (A) to start the chronograph. The chronograph second hand will begin to move.
- Stopping the Chronograph: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Resetting the Chronograph: After stopping, press the lower pusher (B) to reset all chronograph hands to their zero positions.
- Split Time (if applicable): Some chronographs allow for split time measurement. Refer to specific movement instructions if your model supports this. For basic operation, use start, stop, and reset.
Important: Ensure the crown is fully pushed in (position 0) when operating the chronograph to maintain water resistance.
4. Maintenance and Care
4.1 Cleaning Your Watch
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and perspiration.
- For the silicone strap, a damp cloth with mild soap can be used, followed by thorough drying.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish or strap material.
4.2 Water Resistance
This watch is water resistant up to 5 ATM (50 meters / 165 feet). This means it is suitable for short periods of recreational swimming, showering, or washing hands. It is not suitable for diving, snorkeling, or high-impact water sports.
- Always ensure the crown is fully pushed in before any contact with water.
- Do not operate the crown or pushers while the watch is wet or submerged.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
4.3 Battery Replacement
The watch is powered by a quartz movement, which requires a battery. When the battery runs low, the watch may stop or the second hand may jump in irregular intervals (End-of-Life indicator). Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
