2. Setup and Initial Winding
2.1 Unpacking and Inspection
Carefully remove your Omega Seamaster watch from its packaging. Inspect the watch for any visible damage. Ensure all accompanying documents, including the warranty card and instruction manual, are present.

2.2 Manual Winding
Your Omega Seamaster 2222.80 is an automatic mechanical watch. If the watch has stopped, it requires manual winding to initiate movement. To manually wind the watch:
- Unscrew the crown counter-clockwise until it springs out to position 1.
- Turn the crown clockwise approximately 20-30 times. This will provide sufficient power reserve to start the movement.
- The watch will then continue to wind itself through the motion of your wrist while worn. A full power reserve is approximately 48 hours.
2.3 Setting the Time and Date
To set the time and date on your watch:
- Setting the Date: Pull the crown out to position 2. Turn the crown either clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Setting the Time: Pull the crown out to position 3. The seconds hand will stop. Turn the crown to set the hour and minute hands. To ensure precise time setting, synchronize with a reliable time source.
- Once the time and date are set, push the crown back into position 1 and screw it clockwise firmly against the case to ensure water resistance.
3. Operation
3.1 Unidirectional Rotating Bezel
The Omega Seamaster 2222.80 features a unidirectional rotating bezel, which is a crucial safety feature for divers. It rotates only counter-clockwise to prevent accidental increases in dive time. To use the bezel:
- Align the triangle marker on the bezel with the minute hand at the start of your dive or timed event.
- The minute hand will then indicate the elapsed time against the bezel's scale.
- The unidirectional rotation ensures that if the bezel is accidentally moved, it will only indicate a shorter elapsed time, thus providing a safety margin for divers.
3.2 Water Resistance
Your Omega Seamaster 2222.80 is water resistant to 300 meters (1000 feet). This makes it suitable for professional diving, including scuba diving to a depth of 30 meters for up to 2 hours. To maintain water resistance:
- Always ensure the crown is fully screwed down against the case before exposing the watch to water.
- Do not operate the crown or pushers (if present) while the watch is submerged or wet.
- After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it with a soft cloth.
Important: Water resistance is not a permanent condition and may be affected by aging gaskets or accidental impacts. Regular checks are recommended.
4. Care and Maintenance
4.1 Cleaning
To clean your Omega Seamaster watch:
- Use a soft, damp cloth to wipe the case and bracelet.
- For more thorough cleaning, especially after swimming in chlorinated or saltwater, use a mild soap solution and a soft brush, ensuring the crown is fully screwed down. Rinse thoroughly with fresh water afterwards.
- Dry the watch completely with a soft, lint-free cloth.
4.2 Service Intervals
Like any precision instrument, your Omega automatic watch requires periodic servicing to ensure optimal performance and longevity. It is recommended to have your watch serviced by an authorized Omega service center every 5-7 years. This service typically includes:
- Complete disassembly, cleaning, and lubrication of the movement.
- Replacement of worn components.
- Restoration of water resistance (replacement of gaskets).
- Case and bracelet cleaning and refinishing.
4.3 General Precautions
- Avoid exposing your watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes.
- Keep the watch away from strong magnetic fields, which can affect the accuracy of the mechanical movement.
- Protect your watch from impacts and shocks.

5. Troubleshooting
If you encounter issues with your Omega Seamaster, consider the following common solutions before seeking professional service:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running inaccurately. | Insufficient power reserve. | Manually wind the watch by turning the crown clockwise 20-30 times (after unscrewing it to position 1). Wear the watch regularly to keep it wound. |
| Date does not change at midnight. | Time is set to AM instead of PM, or vice-versa. | Advance the time by 12 hours. Ensure the date changes around midnight, not noon. |
| Condensation under the crystal. | Loss of water resistance or extreme temperature change. | Immediately take the watch to an authorized Omega service center. Do not attempt to dry it yourself. |
| Crown cannot be screwed down. | Cross-threaded or debris in the threads. | Do not force it. Gently try to align and screw down. If resistance persists, seek professional assistance to avoid damage and maintain water resistance. |
