Setup

Before wearing your watch, please follow these steps to set the time and date:

  1. Unscrew the Crown: The crown (middle knob on the side) is typically screwed down for water resistance. Gently unscrew it counter-clockwise until it pops out to position 1.
  2. Setting the Date: Pull the crown out to position 2. Turn the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
  3. Setting the Time: Pull the crown out further to position 3. Turn the crown to set the hour and minute hands. Ensure you set the correct AM/PM by observing if the date changes when the hour hand passes midnight.
  4. Secure the Crown: Once the time and date are set, push the crown back into position 1 and screw it clockwise firmly against the watch case to ensure water resistance.

Operating the Chronograph

Your BENYAR 5120 watch features a chronograph (stopwatch) function. The chronograph is operated using the two pushers located above and below the crown.

  1. Start/Stop: Press the top pusher to start the chronograph. Press it again to stop the measurement.
  2. Reset: After stopping the chronograph, press the bottom pusher to reset all chronograph hands back to their zero positions.

The watch also features luminous hands and markers for visibility in low light conditions, and a complete calendar display.

Maintenance

Cleaning

  • Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt.
  • For metal straps, a slightly damp cloth can be used, followed by immediate drying.
  • Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish.

Water Resistance

Your BENYAR 5120 watch has a water resistance rating of 3 ATM (30 meters). This means it is suitable for:

  • Washing hands
  • Exposure to sweat
  • Light rain

IMPORTANT: This watch is NOT suitable for showering, swimming, diving, or any activities involving immersion in water. Ensure the crown is always screwed down tightly to maintain water resistance.

Battery

The watch is powered by a Quartz movement and includes a battery. When the watch stops or the second hand starts skipping, it indicates that the battery needs replacement. It is recommended to have the battery replaced by a professional watch technician to avoid damaging the watch or compromising its water resistance.

Troubleshooting

  • Watch not running: Check if the crown is pushed in. If it is, the battery might need replacement.
  • Incorrect time/date: Refer to the "Setup" section to correctly adjust the time and date.
  • Chronograph hands not resetting to zero: This may require a specific reset procedure or professional adjustment. Consult a watch technician if the standard reset (pressing the bottom pusher after stopping) does not work.
  • Fogging under the crystal: This indicates a loss of water resistance. Avoid further contact with water and have the watch inspected by a professional immediately.
