Introduction
This manual provides comprehensive instructions for the BONEST GATTI BG7003 Tourbillon Skeleton Automatic Wristwatch. This luxury timepiece features a sophisticated automatic tourbillon movement housed within a lightweight carbon fiber case, designed for both precision and aesthetic appeal. The skeletonized design offers a captivating view of the intricate mechanics, while luminous elements ensure readability in low light conditions. Please read this manual carefully to ensure proper use and maintenance of your watch.
The tourbillon, a complex mechanism invented in 1795, was designed to counteract the effects of gravity on a watch's accuracy. This watch incorporates a self-developed hollow-out tourbillon structure, enhancing both its timekeeping precision and its striking visual beauty, solidifying its status as a "King of Watches" in mechanical watchmaking.
Setup
Your BONEST GATTI watch is equipped with an automatic self-winding mechanical movement (BTC-I3) and also supports manual winding.
- Initial Winding: If the watch has stopped or has not been worn for an extended period, it will need to be manually wound. Gently rotate the crown clockwise approximately 20-30 times until you feel resistance. This will provide sufficient power reserve to start the watch.
- Setting the Time: Pull the crown out to the time-setting position. Rotate the crown to adjust the hour and minute hands to the correct time. Once set, push the crown back into its original position to engage the movement.
- Automatic Winding: Once manually wound, the watch will continue to operate and wind itself through the natural motion of your wrist while being worn. For optimal performance, wear the watch regularly.
Operating Instructions
- Power Reserve: The automatic movement provides an approximate 80-hour kinetic energy reserve when fully wound. Regular wear ensures continuous operation.
- Luminous Display: The watch features luminous pointers and case elements that glow in the dark after exposure to light. The intensity and duration of the glow may vary based on exposure time and ambient light conditions.
- Water Resistance (5ATM): This watch is water-resistant up to 5 atmospheres (50 meters). It is suitable for daily use, such as hand washing, rain, and splashes. It is not recommended for swimming, diving, or hot water activities (e.g., showering, sauna) as temperature changes and steam can compromise the seals.
Maintenance
- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and sweat. For the fluoroelastomer strap, a damp cloth with mild soap can be used, followed by thorough drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, and seals.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the movement's accuracy and water resistance.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices) as magnetism can interfere with the mechanical movement and affect timekeeping accuracy.
- Servicing: Mechanical watches benefit from periodic professional servicing (typically every 3-5 years) to ensure optimal performance and longevity.
Troubleshooting
- Watch has stopped: If the watch has stopped, it may simply need winding. Manually wind the watch by rotating the crown clockwise 20-30 times. If it still doesn't start, ensure it's being worn regularly enough for the automatic winding mechanism to function.
- Time is inaccurate: Mechanical watches can be sensitive to shocks and magnetic fields. Check if the watch has been exposed to strong magnets. If inaccuracy persists, professional inspection may be required.
- Condensation under the crystal: This indicates a breach in the watch's water resistance. Immediately seek professional watch repair to prevent further damage to the movement.

User Tips
- Consistent Wear: For automatic watches, consistent daily wear is the best way to keep the movement wound and accurate. If you don't wear it daily, consider manually winding it every couple of days.
- Luminous Charge: To maximize the luminous effect, expose the watch dial to a bright light source (natural or artificial) for a few minutes before entering a dark environment.
- Strap Comfort: The fluoroelastomer strap is designed for comfort and durability. Ensure it's adjusted to a comfortable fit, not too tight or too loose, to prevent skin irritation and allow for proper air circulation.
