4. Setup
4.1 Setting Time and Date
- Adjusting the Date: Gently pull out the crown (the knob on the side of the watch) to the first click position. Turn the crown clockwise or counter-clockwise to set the correct date.
- Adjusting the Time: Pull the crown out further to the second click position. Turn the crown to move the hands and set the correct time. Ensure you set the AM/PM correctly if the watch has a 24-hour indicator or if you are setting the date.
- Securing Settings: Once the time and date are set, push the crown back in completely to its original position. This will start the watch movement and prevent water from entering.
4.2 Strap Adjustment
The watch comes with a strap adjustment tool to help you achieve a comfortable fit. To adjust the length of the stainless steel bracelet:
- Place the watch on a soft surface to avoid scratches.
- Identify the pins on the side of the bracelet links that need to be removed or added.
- Use the provided strap adjustment tool to push out the pins in the direction of the arrows (usually found on the inside of the links).
- Remove or add the necessary links.
- Reinsert the pins to secure the bracelet. Ensure all pins are fully seated.

5. Operating Instructions
5.1 Wearing the Watch
Ensure the watch is securely fastened to your wrist using the bracelet clasp. The clasp is designed for easy and secure closure.
5.2 Water Resistance (5ATM / 50 Meters)
Your SAPPHERO SO2110P watch is rated for 5ATM (50 meters) water resistance. This means it is suitable for:
- Daily use
- Accidental splashes
- Rain exposure
- Washing hands
Important: This watch is NOT designed for swimming, diving, showering, or prolonged water immersion. Avoid operating the crown or pushers when the watch is wet or submerged, as this can compromise the water resistance.


5.3 Luminous Feature
The watch features Swiss luminous technology on its hands and hour markers. To activate the luminescence, expose the watch dial to a bright light source (natural or artificial) for a few minutes. The luminous material will then glow in dark environments, allowing for clear time reading.

6. Maintenance
- Cleaning: Regularly wipe the watch case, crystal, and bracelet with a soft, dry, lint-free cloth to remove dust, sweat, and fingerprints. For the stainless steel bracelet, a slightly damp cloth can be used, followed by immediate drying.
- Avoid Chemicals: Keep your watch away from harsh chemicals, solvents, perfumes, and detergents, as these can damage the watch's finish, seals, and internal components.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the movement and water resistance.
- Storage: When not wearing your watch, store it in its professional waterproof gift box or a soft pouch to protect it from dust, moisture, and impacts.
- Battery Replacement: The quartz movement is powered by a battery. When the watch stops or the second hand starts skipping multiple seconds at a time (End-of-Life indicator), it's time for a battery replacement. This should ideally be done by a qualified watch technician to ensure proper sealing and water resistance.
7. Troubleshooting
- Watch Not Keeping Accurate Time:
Ensure the crown is fully pushed in. If the watch is still not keeping accurate time (the Seiko PC32 movement has an ultra-low time error of ±15 seconds/month), the battery may need replacement, or the watch may require professional servicing. - Strap Noise:
Some users have reported minor noise from the stainless steel bracelet. This is often due to slight friction between the links and may reduce with regular wear. If it persists and is bothersome, a watch specialist might be able to lubricate the links. - Strap Adjustment Tool Broken:
If the included strap adjustment tool is broken or lost, a replacement can be purchased from a watch repair shop or an online retailer. Alternatively, a professional jeweler can adjust the strap for you. - Date Not Changing:
Ensure the time is set correctly, especially the AM/PM cycle. The date typically changes around midnight. If the date is stuck, try manually advancing the time past midnight to see if it engages. If not, the movement may need inspection.
8. User Tips
- The included strap adjustment tool makes it convenient to customize the bracelet length to your wrist size at home.
- The luminous hands and markers provide excellent visibility in low-light conditions, making it easy to read the time at night.
- While the watch offers good value, if you desire micro-adjustments for a perfect fit, consider replacing the bracelet with one that offers this feature, as the original clasp may not have it.
- The watch's elegant design and quality construction make it suitable for both business and casual wear.
