Setup

1. Initial Winding

As an automatic watch, the RT-7930 is powered by the motion of your wrist. If the watch has stopped or has not been worn for an extended period, it may require an initial manual wind to start the movement.

1. Unscrew the crown counter-clockwise until it is free from the case.
2. In position 0 (fully pushed in, unscrewed), turn the crown clockwise approximately 30-40 times. This will provide enough power reserve to start the watch.
3. The second hand should begin to move.

2. Setting Time and Date

1. Setting the Date: Pull the crown out to position 1. Turn the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this is when the date change mechanism is engaged and could cause damage.
2. Setting the Time: Pull the crown out to position 2. The second hand will stop (hacking feature). Turn the crown to set the hour and minute hands. To ensure accurate time setting, set the minute hand a few minutes past the desired time, then turn it back.
3. Once the time and date are set, push the crown back into position 0 and screw it clockwise firmly against the case to ensure water resistance.

3. Adjusting the Bracelet

The stainless steel bracelet features screw-in pins for link removal and adjustment. To resize the bracelet, you will need a small precision screwdriver. Unscrew the pins on the links you wish to remove or add. It is recommended to have this procedure performed by a professional watchmaker to avoid scratching the bracelet or damaging the screws.

Operating Your Watch

Automatic Movement (NH35A)

Your RollsTimi RT-7930 watch is equipped with a Japanese NH35A automatic movement. This movement is self-winding, meaning it gains power from the natural motion of your arm. When fully wound, it has a power reserve of approximately 41 hours. If worn daily, the watch should maintain its power reserve without manual winding.

Water Resistance (100 Meters / 10 Bar)

The watch is water resistant up to 100 meters (10 ATM), making it suitable for swimming, showering, and snorkeling. However, it is not recommended for diving. Always ensure the crown is fully screwed down before exposing the watch to water. Avoid exposing the watch to hot water, steam, or sudden temperature changes, as this can compromise the seals.

Luminous Display

The hands and hour markers of your watch are coated with luminous material, allowing for readability in low-light conditions. Exposure to light will charge the luminous elements, causing them to glow in the dark.

Maintenance

• Cleaning: Wipe the watch case and bracelet regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, ensuring the crown is screwed down. Avoid using harsh chemicals or abrasive materials.
• Avoid Shocks: While durable, mechanical watches are sensitive to strong impacts. Avoid dropping the watch or subjecting it to severe shocks.
• Magnetic Fields: Keep your watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices), as magnetism can affect the accuracy of the mechanical movement.
• Temperature Extremes: Avoid exposing the watch to extreme temperatures, both hot and cold, as this can affect the lubricants and seals.
• Servicing: For optimal performance and longevity, it is recommended to have your automatic watch serviced by a qualified watchmaker every 3-5 years. This includes cleaning, lubricating, and checking the movement and seals.

Troubleshooting

• Watch Not Running: If the watch has stopped, manually wind it by turning the crown clockwise 30-40 times in position 0 (unscrewed). If it still does not start, ensure it is worn regularly to allow the automatic movement to self-wind.
• Inaccurate Time: If the watch is running significantly fast or slow, it may be magnetized or require servicing. Keep it away from strong magnetic fields. If the issue persists, consult a professional watchmaker.
• Date Not Changing: Ensure the time is set correctly, passing midnight to trigger the date change. If the date is stuck, try manually advancing it using the crown in position 1. Avoid adjusting the date between 9 PM and 3 AM.
• Water Inside the Watch: If you notice condensation or water inside the watch, immediately take it to a professional watchmaker. This indicates a compromised seal, and prompt action is necessary to prevent further damage to the movement.
