Setup
1. Unboxing
Carefully remove your watch from its packaging. Inspect the watch for any visible damage. The watch is typically presented in a protective box.

2. Initial Winding
As a mechanical self-winding watch, it may not be running when first unboxed. To initiate the movement, manually wind the watch by rotating the crown clockwise approximately 20-30 times while it is in its normal, pushed-in position. This provides an initial power reserve.
3. Setting the Time
- Gently pull the crown out to its outermost position.
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into its normal, pushed-in position to engage the movement and start the watch.
Operating Your Watch
1. Self-Winding Mechanism
Your Maserati R8821108039 watch is equipped with an automatic mechanical movement. This means that the natural motion of your wrist while wearing the watch will continuously wind the mainspring, providing power to the movement. For optimal performance, wear the watch regularly. If the watch is not worn for an extended period (typically 36-40 hours), it may stop and require manual winding to restart.
2. Water Resistance
This watch has a water resistance rating of 100 meters (10 ATM). This makes it suitable for swimming, showering, and snorkeling. However, it is not recommended for diving. Always ensure the crown is fully pushed in before any contact with water. Do not operate the crown while the watch is wet or submerged.
3. Wearing and Adjusting the Strap
The watch features a leather strap with a tang buckle closure. Adjust the strap to a comfortable fit on your wrist. It should be snug enough to prevent excessive movement but not so tight as to restrict circulation. The strap length is 120 + 80 mm, suitable for a 6-7 inch wrist circumference.

Maintenance
1. Cleaning
To clean your watch, wipe the case and crystal with a soft, dry, lint-free cloth. For the leather strap, avoid excessive moisture and harsh chemicals. If the strap becomes wet, allow it to air dry naturally, away from direct heat or sunlight.
2. Storage
When not wearing your watch, store it in its original box or a watch winder to maintain its power reserve. Keep it away from extreme temperatures, strong magnetic fields, and direct sunlight, which can affect the movement and materials.
3. Water Exposure Precautions
While water resistant, prolonged exposure to hot water (e.g., hot tubs, saunas) or chemical substances (e.g., detergents, perfumes) can compromise the watch's seals and materials. Always rinse the watch with fresh water after exposure to salt water and dry it thoroughly.
4. Professional Servicing
Mechanical watches benefit from periodic professional servicing, typically every 3-5 years. This includes cleaning, lubrication, and adjustment of the movement, as well as checking and replacing seals to maintain water resistance.
Troubleshooting
- Watch Not Running: If the watch has stopped, it likely needs to be wound. Manually wind the watch by rotating the crown clockwise 20-30 times. If it still does not start, ensure the crown is fully pushed in.
- Time Inaccuracy: Mechanical watches are not as precise as quartz watches. A deviation of +/- 10-30 seconds per day is generally considered acceptable. If the watch is consistently losing or gaining significant time, it may require professional adjustment or servicing.
- Condensation Under Crystal: If you notice condensation under the crystal, this indicates a breach in the watch's water resistance. Immediately take the watch to a qualified watchmaker for inspection and repair to prevent further damage to the movement.
