3. Setup
3.1 Initial Charge
Your MVMT Cali Diver Solar Watch is powered by light. For optimal performance, expose the watch dial to a strong light source (natural sunlight is best) for several hours before initial use. A full charge can take up to 8 hours in direct sunlight or significantly longer under artificial light.
3.2 Setting Time and Date
- Unscrew the Crown: Locate the crown on the right side of the watch case. Rotate it counter-clockwise until it is unscrewed and pops out slightly.
- Set Date (Position 1): Gently pull the crown out to the first click. Rotate the crown clockwise or counter-clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
- Set Time (Position 2): Pull the crown out to the second click. The second hand will stop. Rotate the crown to set the hour and minute hands. To ensure accuracy, set the time a few minutes ahead and then push the crown back in when a time signal (e.g., from a radio or phone) reaches the desired time.
- Secure the Crown: Once time and date are set, push the crown back in fully and screw it clockwise tightly against the watch case. This is crucial for maintaining water resistance.

4. Operating
4.1 Water Resistance (10 ATM / 100 Meters)
Your MVMT Cali Diver watch is rated for 10 ATM (Atmospheres) or 100 meters of water resistance. This means it is suitable for everyday use, swimming, snorkeling, and recreational diving. Ensure the crown is always fully screwed down before any exposure to water.
Important: Water resistance is not a permanent condition and may eventually be compromised by impacts, temperature changes, or aging gaskets. Avoid exposing the watch to hot water, steam, or sudden temperature changes (e.g., jumping into cold water after being in a hot tub), as this can damage the seals.

4.2 Unidirectional Rotating Bezel
The bezel on your Cali Diver watch rotates in one direction (counter-clockwise) to prevent accidental lengthening of timed events. To use it, rotate the bezel so the triangle marker aligns with the minute hand. The minute hand's position on the bezel will then indicate the elapsed time.
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch, wipe the case and bracelet regularly with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by a dry one. Avoid using harsh chemicals or abrasive materials.
5.2 Storage
When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. For solar watches, ensure it receives occasional light exposure to prevent the battery from fully discharging.
5.3 Battery Life
The solar cell in your watch is designed for long-term use. With regular exposure to light, the watch should operate continuously. If the watch stops, expose it to bright light for several hours to recharge. The power reserve can last for several months in darkness once fully charged.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or hands do not move. | Insufficient charge. | Expose the watch dial to strong light (preferably sunlight) for several hours. |
| Date changes at noon instead of midnight. | AM/PM setting is incorrect. | Advance the time by 12 hours. |
| Condensation inside the crystal. | Water resistance compromised or extreme temperature change. | Immediately take the watch to an authorized service center. Avoid further water exposure. |
| Crown does not screw in. | Cross-threaded or debris. | Ensure the crown is aligned correctly before screwing. Do not force. If issue persists, seek professional help. |
