2. Initial Setup
2.1 Setting the Time and Date
- Pull out the crown: Locate the crown on the right side of the watch case. Gently pull it out to the second click position.
- Set the time: Rotate the crown clockwise or counter-clockwise to move the hour and minute hands to the desired time. Ensure the AM/PM is correctly set if your watch has a date function that changes at midnight.
- Set the date: If your watch has a date display, push the crown in one click (to the first click position). Rotate the crown to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Push in the crown: Once the time and date are set, push the crown back into its original position against the watch case. This will start the watch movement.

2.2 Solar Charging
This watch features a solar-powered movement. For initial charge or if the watch has stopped, expose the dial to a strong light source (natural sunlight is ideal) for several hours. Avoid extreme heat. Regular exposure to light will maintain the charge.
3. Operating Instructions
3.1 Timekeeping
Your Timex Expedition North Sierra watch is designed for accurate timekeeping. The hour, minute, and second hands continuously display the current time. The date window, if present, updates once every 24 hours.
3.2 Water Resistance
This watch is water resistant up to 200 meters (660 feet). This rating makes it suitable for swimming, showering, and recreational diving.Important: Do not operate the crown or pushers while the watch is wet or submerged, as this can compromise the water resistance. Ensure the crown is fully pushed in before exposing the watch to water.

3.3 Rotating Bezel
The watch features a unidirectional rotating bezel. This bezel can be used to measure elapsed time, typically for diving or other timed activities.
- To measure elapsed time: Rotate the bezel so that the zero marker aligns with the minute hand. As time passes, the minute hand will point to the elapsed time on the bezel.
4. Care and Maintenance
