Setup and Initial Adjustment
1. Setting the Time
- Pull the crown out to position 2 (the furthest position). The second hand will stop.
- Turn the crown to set the hour and minute hands. Ensure the AM/PM is correctly set if your watch has a 24-hour indicator or if setting the date.
- Push the crown back into position 0 (normal position). The second hand will resume movement.
2. Setting the Date
- Pull the crown out to position 1 (the first click).
- Turn the crown clockwise or counter-clockwise (depending on the movement) to set the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement. If the date needs adjustment during this period, first set the time outside this range, adjust the date, then reset the time.
- Push the crown back into position 0.
3. Adjusting the Bracelet
The stainless steel bracelet may require adjustment for a comfortable fit. This typically involves removing or adding links. It is recommended to have this procedure performed by a qualified watchmaker or jeweler to prevent damage to the bracelet or watch.
Operating the Chronograph Function
Your watch is equipped with a chronograph function for measuring elapsed time.
- Start/Stop: Press the upper pusher (button A) to start the chronograph. Press it again to stop the chronograph.
- Reset: While the chronograph is stopped, press the lower pusher (button B) to reset all chronograph hands to their zero positions.
Water Resistance
This watch has a water resistance rating of 50 meters (5 ATM). This rating means the watch is suitable for short periods of recreational swimming. It is not suitable for diving, snorkeling, or high-impact water sports. 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.
Maintenance and Care
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and dirt. For the stainless steel case and bracelet, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
- Temperature: Avoid exposing the watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes.
- Shocks: While durable, avoid strong impacts or shocks to the watch.
- Magnetic Fields: Keep the watch away from strong magnetic fields, as they can affect the accuracy of the quartz movement.
- Battery Replacement: The watch is powered by a quartz movement and requires a battery. When the battery is depleted, the watch will stop. Battery replacement should be performed by a qualified watchmaker to ensure proper sealing and water resistance.
- Service Intervals: Regular servicing every 3-5 years by an authorized service center is recommended to maintain optimal performance and water resistance.
