2. Setup
2.1 Setting the Time
- Pull out the Crown: Locate the small knob (crown) on the right side of the watch case. Gently pull it out to the first position.
- Adjust the Time: Rotate the crown clockwise or counter-clockwise to move the hour and minute hands to the desired time.
- Push in the Crown: Once the correct time is set, push the crown back into its original position. This will start the watch movement.

2.2 Adjusting the Stainless Steel Band (Sliding Clasp)
The NIXON Time Teller A045 features a sliding clasp bracelet for adjustable sizing. A band sizing tool is typically included with your watch.
- Identify the Clasp: Locate the sliding clasp on the watch band.
- Open the Clasp Lock: Use the provided band sizing tool (or a small, flat-head tool) to gently pry open the small locking mechanism on the clasp. Insert the tip into the window of the clasp and apply slight pressure to lift the lock.
- Adjust the Clasp Position: Once unlocked, slide the clasp along the bracelet to achieve the desired fit. Slide it towards the watch case to make the band smaller, or away from the case to make it larger.
- Secure the Clasp: Once the desired position is found, firmly press the locking mechanism back down until it snaps into place. Ensure it is fully secured to prevent accidental opening.

Caution: Do not use the bar on the clasp as leverage when opening the lock, as this may bend the pin and render the clasp non-functional. If the clasp is damaged, contact customer support for assistance.

4. Maintenance
4.1 Water Resistance
Your NIXON Time Teller A045 watch is rated for 100 meters (10 ATM) water resistance. This means it is suitable for showering, swimming, and snorkeling. It is not recommended for high-impact water sports or diving beyond shallow depths.
- Always ensure the crown is fully pushed in before exposing the watch to water.
- Avoid operating the crown while the watch is wet or submerged.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly with a soft cloth.
4.2 Cleaning
To maintain the appearance of your watch:
- Wipe the watch case and band regularly with a soft, damp cloth.
- For stainless steel bands, a soft brush can be used to clean between the links.
- Avoid using harsh chemicals, solvents, or abrasive cleaning materials, as these can damage the finish.
4.3 Battery Replacement
The watch uses 1 Lithium Ion battery (included). Battery life varies depending on usage. When the watch stops or the second hand begins to jump erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure water resistance is maintained.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running slow. | Low battery. | Replace the battery (professional service recommended). |
| Condensation inside the crystal. | Temperature change or moisture ingress. | If condensation persists, seek professional service immediately to prevent damage. |
| Watch band is too loose/tight. | Incorrect clasp adjustment. | Refer to Section 2.2 for band adjustment instructions. |
