Setup and Initial Use
Winding the Watch
Your Timex Expedition North Field Post Mechanical watch is powered by a hand-wound mechanical movement and does not require a battery. To wind the watch:
- Ensure the crown is pushed in completely against the watch case.
- Turn the crown clockwise until you feel a slight resistance. This indicates the mainspring is fully wound.
- It is recommended to wind the watch at approximately the same time each day to maintain consistent operation.

Setting the Time
To set the time on your watch:
- Gently pull the crown outwards to the time-setting position.
- Turn the crown clockwise or counter-clockwise to move the hands to the correct time.
- Once the time is set, push the crown back in firmly against the watch case to engage the movement and ensure water resistance.
Operating Instructions
Water Resistance
This watch is water-resistant to 100 meters (330 feet). This rating makes it suitable for snorkeling and swimming. It is not recommended for diving activities.
- 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.
Luminous Display
The hands and dial markings feature luminous material for visibility in low-light conditions. Exposure to light will charge the luminous elements, allowing them to glow in the dark.
Maintenance and Care
Proper care will help maintain the appearance and function of your watch.
- Cleaning: Wipe the watch case and bracelet with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, crystal, or seals.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the movement and water resistance.
- Magnetic Fields: Keep the watch away from strong magnetic fields, as these can interfere with the accuracy of the mechanical movement.
- Sapphire Crystal: The watch features a scratch-resistant sapphire crystal. While highly durable, it is not entirely impervious to damage. Avoid impacts and abrasive surfaces.

Troubleshooting
If you encounter issues with your watch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops running | Not sufficiently wound. | Wind the watch fully by turning the crown clockwise until resistance is felt. Ensure daily winding. |
| Watch runs too fast or too slow | Exposure to magnetic fields; movement requires adjustment. | Keep the watch away from strong magnets. If accuracy issues persist, contact Timex customer support for service. |
| Crown is stiff or difficult to pull/turn | Accumulation of dirt; manufacturing variation. | Gently try to operate the crown. If it remains stiff or difficult to use, avoid forcing it and contact Timex customer support. |
| Water ingress | Crown not fully pushed in; seals compromised. | Ensure the crown is always fully pushed in before water exposure. If water is observed inside the watch, seek immediate professional service to prevent further damage. |
