Setup
Adjusting the Watch Band:
Your OLEVS watch comes with a 316L stainless steel strap and a free band adjustment tool. To ensure a comfortable fit, you may need to remove or add links. It is recommended to have this procedure performed by a professional watchmaker or jeweler to avoid damage to the band or watch.
Initial Time Setting:
- Unscrew the Crown (if applicable): Some waterproof watches have a screw-down crown. Gently unscrew it counter-clockwise until it pops out.
- Pull the Crown Out: Pull the crown out to the first or second click position (refer to the "Operating Instructions" section for specific crown positions for time/date/moon phase adjustment).
- Set Time: Rotate the crown to set the hour and minute hands to the correct time. Ensure to account for AM/PM if setting the date.
- Push Crown Back In: Once the time is set, push the crown back into its original position. If it's a screw-down crown, gently push and screw it clockwise until it is securely tightened to maintain water resistance.
Operating Instructions
Crown Functions:
- Position 0 (Normal Position): Watch is running. For screw-down crowns, ensure it is fully tightened for water resistance.
- Position 1 (First Click): Typically used for quick date or moon phase adjustment. Rotate the crown clockwise or counter-clockwise to adjust.
- Position 2 (Second Click): Used for setting the time. Pull the crown out to this position, and the second hand may stop (hacking feature). Rotate to set time.
Chronograph Operation:
The chronograph function allows you to measure elapsed time. Your watch has two push-buttons on the side, typically above and below the crown.
- Start/Stop: Press the upper push-button to start the chronograph. Press it again to stop.
- Reset: While the chronograph is stopped, press the lower push-button to reset all chronograph hands back to their zero positions.
Moon Phase Adjustment:
The moon phase display tracks the lunar cycle. To set it, pull the crown to the first click position and rotate it (direction may vary by model) until the moon phase indicator shows the current phase of the moon. Refer to a reliable moon phase calendar for accuracy.
Luminous Function:
The hands and markers on your OLEVS watch are treated with a luminous material. To activate their glow in the dark, expose the watch dial to a bright light source (e.g., sunlight or a strong lamp) for a few minutes. The intensity and duration of the glow will depend on the exposure time and light intensity.
Maintenance
- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt. For the stainless steel band, a slightly damp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals or abrasive materials.
- Water Resistance: While your watch is 3ATM water resistant, it is designed for daily life waterproofing only. Avoid exposing it to hot water, steam (e.g., showers, saunas), or prolonged submersion. Always ensure the crown is fully pushed in and, if applicable, screwed down tightly to maintain water resistance.
- Temperature Extremes: Avoid exposing your watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect the movement and seals.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones) as they can affect the accuracy of the movement.
- Impact: Avoid dropping the watch or subjecting it to strong impacts, which can damage the internal components or the crystal.
- Battery Replacement: The watch uses a high-quality battery. When the battery runs low, the watch may stop or lose accuracy. It is recommended to have the battery replaced by a professional watchmaker to ensure proper sealing and prevent damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is losing time. | Low battery; exposure to strong magnetic fields; physical shock. | Replace battery (professional recommended); demagnetize watch (professional recommended); avoid impacts. |
| Condensation under the crystal. | Exposure to extreme temperature changes; crown not fully pushed in/screwed down. | Avoid sudden temperature changes; ensure crown is secure. If condensation persists, seek professional service. |
| Chronograph hands do not reset to zero. | Needs calibration; internal mechanism issue. | Consult a professional watchmaker for calibration or repair. |
| Date/Moon phase not changing correctly. | Incorrect setting; setting during "danger zone" hours (typically 9 PM - 3 AM). | Reset date/moon phase outside of the "danger zone" hours. If issue persists, seek professional service. |
